<Abstract>

This paper investigates the effects of characteristics of band-pass filter to operation of class DE inverter. Two kinds of band-pass filter are applied to the design of class DE inverter, and circuit experiments are carried out. As the result, output voltage characteristic of the class DE amplifier with band-pass filter is very flat. Because of output characteristics of band-pass filters are flat at the nominal frequency. Moreover, when the operating frequency decreases from nominal frequency, both the class DE inverter with band-pass filters achieve ZVS.
