    Abstract :

    The paper proposes a novel SVPWM technique involving double switching of a phase in the sampling period of the reference vector. The work identifies all possible switching sequences, which result in same average switching frequency as conventional space vector PWM (CSVPWM). The switching sequences are arranged to clamp a phase when the current waveform at its peak value. The proposed Advanced Double switching PWM (ADSPWM) reduces the switching loss and current ripple in motor drives, compared to the existing bus clamped PWM. An insulated gate bipolar transistor (IGBT) based 2 KVA voltage source inverter (VSI) with DC bus voltage of 400 V is designed and implemented with an 8-bit PIC microcontroller (PIC18F452). The superior switching loss characteristics of the ADSPWM technique over the existing SVPWM is experimentally verified on a 415V, 2hp induction motor drive.
