本文给出了任意占空比下D类零电压开关逆变器的稳态解析表达式，并给出了设计实例。得到的表达式包括稳态电压和电流波形，输出功率能力，峰值开关电压，峰值开关电流，输出功率和功率转换效率作为占空比的函数。此外，由于开关器件的反并联二极管的开关定时余量可以预测从分析结果。通过与PSpice仿真和电路实验的定量协议，验证了解析表达式。
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.
