The authors explain the operation of a 100 W half-bridge resonant DC-DC converter, the method of determining the LC constants, and the condition of gate drive for achieving no-loss switching. Since the circuit operation is of a zero-volt-switching type, the switching loss at turn-off as well as turn-on can be zeroed by strengthening the gate drive circuit. It is confirmed that the LC constants can be determined by using a simple circuit model, and that setting a low resonant capacitor voltage is effective for reducing the main circuit loss. The characteristics of some DC-DC converters trial-manufactured on the basis of these results are shown.<>
