| Abstract: | The full-digital PWM waveform generating chip SA828 can be designed to produce 3 phase PWM waveform with high quality under the control of micro-processor. Its accuracy and temperature stability is much better than traditional analogue method. The principle and control method was introduced, and a design sample of hardware and software applied on variable frequency system was given in this paper. |
