<Abstract>

In this paper, we present the analytical expression of phase-controlled class-D inverter at any duty ratio. By considering the body-diode of MOSFET effects and harmonic components of resonant current, analytical expression of phase-controlled class-D inverter at any phase shift and any duty ratio can be obtained. The validity of the analytical expression was confirmed by PSpice simulation.
