摘要

研究了程序脉宽调制(PWM)与常规脉宽调制(PWM)在各种DC-DC转换电路波形中降低峰值谐波幅度的效果。发现各种光谱加权可以显著降低。在实验装置中，在商用功率转换器中实现了将峰值谐波功率降低到大约九分之一。

On optimal programmed PWM waveforms for DC-DC converters

The use of programmed pulse width modulation (PWM) versus regular PWM to reduce the magnitude of the peak harmonic in various DC-DC converter circuit waveforms was investigated. Significant reduction was found possible with a variety of spectral weighting. In the experimental set-up, a reduction in the power of the peak harmonic to approximately one-ninth was achieved in a commercially available power converter.<>
