Abstract
A DC-AC converter has two half-bridge circuits using an input feedback signal and an input clock signal together with time delay circuits, wherein one of the half-bridge circuits drives one pair of corresponding FETs and the other half-bridge circuit drives the other pair of corresponding FETs. The DC-AC converter includes: a Direct Current (DC) power source; a switching unit which includes a plurality of Field Effect Transistors (FETs) for changing paths of Direct Current (DC), so as to convert the DC to Alternating Current (AC); a transformer for transforming a voltage input from the switching unit; a load unit connected to the transformer; and a signal control unit for simultaneous parallel control of the FETs in the switching unit.
