Abstract- Pulse Width Modulation (PWM) is a common technique used in many different applications of 3-phase voltage source inverter. This paper presents a pulse generation of SPWM technique for three-phase voltage source inverter using dsPIC33FJ16GS402 controller. Logic for implementing SPWM technique is described. The carrier signal frequency is designed for 20 kHz with varied modulation index (Ma) and the fundamental signal frequency is designed for 50Hz. Simulation results of controller circuit, carried out in PROTEUS simulator are shown, Also mentioned in developed driver and controller cards in this paper. An experimental result presented in this paper shows the effectiveness of pulse generation Technique.see more
