This paper presents steady-state analytical expressions of the class-D zero-voltage switching inverter at any duty ratio along with a design example. The obtained expressions include stead-state voltage and current waveforms, output power capability, peak switch voltage, peak switch current, output power, and power conversion efficiency as functions of the duty ratio. Additionally, switching-timing allowance due to antiparallel diodes of switching devices can be predicted from the analytical results. The analytical expressions are verified by showing quantitative agreements with PSpice simulations and circuit experiments. [ABSTRACT FROM PUBLISHER]
