| Abstract: | In this paper we introduce a variable-frequency system which uses the SCM to control a pulse width modulator of triphase sine wave,and tell readers how to use integrated chip SA8281 and IR2110.This variable-frequency power sources has a simple structure and costs little.It can change frequency from 0 to 333HZ and its carrier frequency is 5kHZ.It also has the perfect function of error protection.In this paper we also give the experimental result. |
