The inverter is an electronic circuit that converts direct current into alternating current. Inverters are used to produce continuous power source, the transmission of direct electricity power and speed control of unsynchronously motors. Inverter is named by turning (inverted) dc voltage, in contrast to the rectifier, which converts AC to DC.
In a simple inverter circuit, DC voltage source is connected to the transformer via the terminals at the center of the primary. A switch is rapidly shifting from one position to another, which allow electric current to flow back to the DC source through two alternative views, one by one end of the primary and the other through the other end of the primary. Changing the direction of current in the primary transformer produces alternating current in the secondary.
