本文分析了D类逆变器开关器件栅极驱动采用不规则驱动方式时的情况。重点从波形、谐波、低频分量、输出功率和等效直流电阻等方面进行了分析，并对其进行了数值分析和讨论。分析了6种不同Q因子（0.1 ~ 20）下D类逆变器的216种驱动模式，构建了6种逆变器的4种优良模型，并进行了电路实验。计算波形与实验结果进行了比较。两者在时域和频域上都很好地吻合。分析结果表明，一种新的非规则驱动模式控制方法是可行的。尽管是不连续控制，但在某些范围内，使用选定的驱动模式，输出功率或电压可以像连续一样严格改变
This paper presents an analysis of Class D inverter when irregular driving patterns are given to the gate drive of the switch devices. The analysis has been carried out with focusing on the waveforms, harmonics, low-frequency components, output power, and equivalent dc resistance, which are numerically analyzed and discussed. Class D inverters with six different Q factors from 0.1 to 20 are analyzed about 216 driving patterns for each Q. Superior four models of the six inverters are built and tested in circuit experiments. The calculated waveforms are compared to the experimental results. Both of them are agreed well in time domain and frequency domain. Analytical results show a possibility of a novel control method with irregular driving patterns. In spite of discontinuous control, the output power or voltage can be strictly changed as if continuous using the selected driving patterns in some ranges
