摘要

本文提出了一种d类高频功率放大器/逆变器的电能质量评价方法。推导了谐振电路输入端的实功率、无功功率、复功率、表观功率、畸变功率和非有功功率，并以频率的函数表示。同时确定了总谐波失真和功率因数。对放大器直流输入处的电能质量进行了类似的分析。实验结果验证了理论的正确性。结果表明，d类逆变器的输入电流中含有显著的交流分量，对实际直流输入功率没有贡献，导致畸变功率高，总谐波失真高，功率因数差。设计、制作了d类逆变器并进行了测试，验证了理论的正确性。

Power Quality in Class-D High-Frequency Power Inverter: Input and Resonant Tank Distortion Power, Total Harmonic Distortion, and Power Factor

This paper presents a power quality evaluation of the Class-D high-frequency power amplifier/inverter. The real, reactive, complex, apparent, distortion, and non-active powers at the input of the resonant circuit are derived and illustrated as functions of frequency. Also, the total harmonic distortion and power factor are determined. Similar analysis of the power quality at the dc input of the amplifier is given. Experimental results are given to verify the theory. It is shown that the input current of the Class-D inverter contains a significant ac component that does not contribute to the real dc input power, resulting in high distortion power, high total harmonic distortion, and poor power factor. The Class-D inverter was designed, built and tested to verify the theory.
