结果表明:方波和正弦波调幅磁场的感应热功率都与调幅波频率无关。
The results show that the induction heat power of magnetic field amplitude-modulated with sine wave and square wave is unrelated to the frequency of modulating wave.
本文在分析了几种SPWM调制方法的基础上,将基于对称采样法的SPWM调制算法应用于本设计中,产生了可调频调幅的正弦波脉宽调制信号。
The SPWM algorithm using symmetrical sample in this controller, can alter its frequency and amplitude. The good performance of the BLDC Motor controller using DSP is verified by the experiment.
