| Abstract: | SPWM (Sine Pulse Width Modulation) and CPWM (Cosine Pulse Width Modulation) signals with fixed switching angles are generated by microprocessor. After being amplified by their driving circuits and power amplifiers, the signals are converted to three-phase AC by Scott connected transformers. The output voltage regulation is realized at its DC input. This inverter has simple construction, high reliability and low HMD. |
