Abstract
An exemplary direct current to alternating current converter includes a pulse width modulator having a plurality of pulse signal outputs that can provide a plurality of pulse signals, a driving circuit having a plurality of switching units, and a transformation circuit having a plurality of transformers. Each of the switching units includes a P-type transistor and an N-type transistor. Each pulse signal output is electrically connected to the P-type and N-type transistors of one of the switching units. Each of the transformers is connected to two of the switching units, and the P-type transistors and the N-type transistors of the two switching units are not switched on simultaneously.
