A Light Emitting PVC drive power was designed. A mothed of calcuting unipolar SPWM based on equivalent area algorithm was introduced, and the parameters using PIC16F883 for generating Sinusoidal Pulse Width Modulated signal were analyzed. Then a program for auto calculating the parameters using by PIC16F883 to generate SPWM signal was designed. The half-bridge inverter circuit based on IR2110 chip was successful y driven by the signal in generating a voltage of 850 Hz110 V AC, and the LEP normal wok was driven.
