Design of Three-phased SPWM Based on AT89C52

摘要

According to the AT89C52 and the area equivalent principle, a three phase SPWM algorithm based on the 8 bit single chip is obtained. Through computer programming, three-phase SPWM wave generated by a single chip microcomputer is applied to the circuit of the static reactive power generator. The result shows that this method is feasible and can reduce the cost of SVG.
