摘要

设计并实现了一种逆变器，该逆变器采用脉冲频率调制(PFM)将恒定的直流电压转换为幅度和频率可控的交流电压。利用构建的模拟PFM图形的软件程序，研究了载波与参考频率之比、调制深度和脉宽等不同参数对生成的PFM图形谐波含量的影响。根据这些研究，确定了应用于逆变器的PFM的合适参数。

Application of pulse frequency modulation for voltage frequency control of inverters

An inverter is designed and implemented, that applies pulse frequency modulation(PFM) in order to shape a constant DC voltage into an AC voltage with controllable magnitude and frequency. The authors investigated the effect of different parameters on the harmonic content of the generated PFM pattern, such as the effect of the ratio of carrier to reference frequency, modulation depth and pulse width using a software program constructed to simulate PFM patterns and calculate the corresponding harmonic content. According to these investigations an appropriate decision is taken about the suitable parameters of the PFM applied to the inverter.
