TRANSFORMER
___________
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits.
Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits. Transformers can also be used for isolation, where the voltage in equals the voltage out, with separate coils not electrically bonded to one another.
Transformer look like traffic on round
🚔 circle , lets look example 🔓⛽
Since the invention of the first constant-potential transformer in 1885, transformers have become essential for the transmission, distribution, and utilization of alternating current electric power.A wide range of transformer designs is encountered in electronic and electric power applications. Transformers range in size from RF transformers less than a cubic centimeter in volume, to units weighing hundreds of tons used to interconnect the power grid.
Various specific electrical application designs require a variety of
transformer types. Although they all share the basic characteristic transformer principles, they are customized in construction or electrical properties for certain installation requirements or circuit conditions.
In electric power transmission, transformers allow transmission of electric power at high voltages, which reduces the loss due to heating of the wires. This allows generating plants to be located economically at a distance from electrical consumers. All but a tiny fraction of the world's electrical power has passed through a series of transformers by the time it reaches the consumer.
In many electronic devices, a transformer is used to convert voltage from the distribution wiring to convenient values for the circuit requirements, either directly at the power line frequency or through a switch mode power supply.
Signal and audio transformers are used to couple stages of amplifiers and to match devices such as microphones and record players to the input of amplifiers. Audio transformers allowed telephone circuits to carry on a two-way conversation over a single pair of wires. A balun transformer converts a signal that is referenced to ground to a signal that has balanced voltages to ground, such as between external cables and internal circuits. Isolation transformers prevent leakage of current into the secondary circuit and are used in medical equipment and at construction sites. Resonant transformers are used for coupling between stages of radio receivers, or in high-voltage Tesla coils.

ADAPTER
_________
An adapter or adaptor is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one connector to another.
1. adapter in its internal style guide, namely, use adaptor when referring to devices and adapter when referring to people. 1 : one that adapts. 2a : a device for connecting two parts (as of different diameters) of an apparatus. b : an attachment for adapting apparatus for uses not originally intended. How it works. A simple AC adapter consists of a transformer, a rectifier, and an electronic filter. The transformer initially converts a relatively high-voltage alternating current that is supplied by an electrical outlet to a lower voltage suitable for the device being powered.An adapter card (also known as an expansion card) is simply a circuit board you install into a computer to increase the capabilities of that computer. They are large because of the physical size of the components that they need. With newer technology, and lower power devices, some AC adapters no longer do that, but for larger devices that is likely to be an issue for years to come. One solution is to use a cable extension between the AC outlet and the adaptor .
2. A SanDisk adapter is a PC card you insert into your laptop that lets you transfer data between devices such as phones. The SanDisk adapter lets you insert the phone's memory card to transfer data.
AC-to-DC adapters
A "power cube"-type AC adapter
An AC-to-DC power supply adapts electricity from household mains voltage (either 120 or 230 volts AC) to low-voltage DC suitable for powering consumer electronics. Small, detached power supplies for consumer electronics are called AC adapters, or variously power bricks, wall warts, or chargers.
Computer adapters
A host controller connects a computer to a peripheral device, such as a storage device, network, or human interface device. As a host controller can also be viewed as bridging the protocols used on the buses between peripheral and computer, and internally to the computer, it is also called a host bus adapter. Likewise, specific types may be called adapters: a network interface controller may be called a network adapter, and a graphics card a display adapter.
Adapters for external ports
Adapters (sometimes called dongles) allow connecting a peripheral device with one plug to a different jack on the computer. They are often used to connect modern devices to a legacy port on an old system, or legacy devices to a modern port. Such adapters may be entirely passive, or contain active circuitry.
A common type is a USB adapter.
One kind of serial port adapter enables connections between 25-contact and nine-contact connectors,[2] but does not affect electrical power- and signalling-related attributes.

CONVERTER Electronics
_____________________
Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC).
4-Different Power Converters
Introduction to Power Electronic Converters.
AC to DC Converters or Rectifiers. Uncontrolled Diode Rectifiers. Single phase half-wave rectifier. ...
DC to DC Converters. Step-down Chopper or Buck converter. Step-up Chopper or Boost converter. ...
AC to AC Converters. AC/AC Voltage Converters. ...
DC to AC Converters or Inverters.
These converters are used to regulate and shape an electrical signal in the required form. Among these converters, AC–DC converters, commonly known as rectifiers, are used extensively in renewable energy systems such as grid-connected DC microgrids, grid-connected solar photovoltaic energy conversion systems, etc.
Some examples of uses for power electronic systems are DC/DC converters used in many mobile devices, such as cell phones or PDAs, and AC/DC converters in computers and televisions. Large scale power electronics are used to control hundreds of megawatt of power flow across our nation.
The big difference between an adapter and a converter is electricity. While the purpose of an adapter is to simply help the plugs on your electronics fit into (or more aptly, adapt to the shape of) foreign outlets, a converter's job is to change the voltage found in an outlet to match that of your devices.
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching.
Many common persovonal devices--like an iPhone charger, laptops, and cameras--that people like to travel with can be easily powered up abroad with a simple plug adapter because they are dual voltage devices. Plug adapters do not convert electricity; converters do that, but you won't need one for a dual voltage device.
iPhone's charger works both on 120 volt and 220 volt. ... A plug adaptor is all you need, the charger itself can run on any voltage between 100 and 240.
Full converter : In the same circuit as above uses 4 thyristors (which is like a diode which turns on only when an external signal is given by us) So that we can control the output voltage of the converter dc output. Semi converter : In the same circuit , 2 thyristors and 2 diodes are used.
Power electronics is the application of solid-state electronics to control and convert one form of electrical power to another form such as converting between AC and DC or changing the magnitude and phase of voltage and current or frequency or combination of these. Power electronics converters are widely used in myriad power conversion applications from fraction of volt and power to tens of thousands of volts and power levels. Sometimes it involves multistage power conversion with two or more converters connected in series/parallel or in cascade fashion. The application might be different, but the end goal is primarily driven by five major aspects, such as: energy efficiency, power density, cost, complexity, and reliability, which also influence each other to some extent. In this chapter, various power electronic convertors (AC-DC, DC-AC, DC-DC, and AC-AC) and commonly used circuit and topologies are introduced with their general operating principle.

A device that converts direct current electricity to alternating current either for stand-alone systems or to supply power to an electricity grid.
An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed. ... In inverter type air conditioners, temperature is adjusted by changing motor speed without turning the motor ON and OFF.
According to the output characteristic of an inverter, there can be three different types of inverters.
Square Wave Inverter.
Sine Wave Inverter.
Modified Sine Wave Inverter.
The applications areas of inverters such as:
Adjustable-speed ac motor drives.
