In one simple inverter circuit, DC power is connected to a through the center tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary and then the other. The alternation of the direction of current in the primary winding of the transformer produces
