| Abstract: | The paper is about formation and working principles of PWM for frequency conver-sion and speed governing system with automatic compensation of low frequency voltage by applica-tion of large, middle scale IC to integrate main circuit and control circuit. And emphasis is made on analysis and discussion about M57940L driving circuit and automatic compensation of low frequencyvoltage. Finally experimental data and waveforms of operation of the system are given out. The conclusion can be drawm: The system has simplified structure, low cost, fine adaptabilityand operational reliability. And the system can be widely used in production. |
