What is an inverter?

Answer:

The power supply from direct current to alternating current is called inverter. It is usually the use of thyristor circuits to convert direct current into alternating current, which is defined as an inverting process corresponding to rectification. For example: the application of thyristor electric locomotive, when the downhill, the DC motor as a generator brake operation, the locomotive potential into electric energy, back to the AC network. Another example is the running of the DC motor, to make it quickly braking, but also allows the motor to run as a generator, the motor kinetic energy into electricity, back to the power grid.
The principle of the inverter is that the thyristor circuit converts the direct current into alternating current, which is defined as the inverse process of rectification.
The thyristor (Thyristor): thyristor short, also called silicon controlled rectifier, previously referred to as SCR; in 1957 the United States Ge Corp developed the first thyristor products in the world, and in 1958 its commercialization; thyristor PNPN four layer semiconductor structure, it has three pole: anode, cathode and gate; characteristics of the silicon rectifier thyristor, can work under high voltage and high current conditions, and its working process can be controlled and is widely used in controllable rectifier, AC voltage, contactless electronic switch, inverter and inverter in electronic circuits.
