随机脉宽调制可以把非连续的输出电压频谱连续化,通过试验提出了一种基于 INTEL80C196MC单片机的改进位置随机脉宽调制策略,并对位置随机和改进的位置随机的相电压频谱进行了比较.
Random pulse width modulation (PWM) can continuously discontinuously output the frequency spectrum of the output voltage. An improved random pulse width modulation strategy based on the INTEL80C196MC microcontroller is proposed. The stochastic phase voltage spectrum with random location and improved location is compared.
