This paper presents the carrier based discontinuous space vector pulse width modulation (DSVPWM) for two-phase four-leg voltage source inverters (VSI) fed resistive and inductive loads. This proposed technique is focused on the switching losses and output current ripple reduction in each phase-leg of inverter which does not depends on the lagging and leading power factor load. In addition, the carrier based DSVPWM is modified from conventional two-phase four-leg VSI by replacing the zero space vector in each switching sequence. This proposed discontinuous modulation strategy has 180 degrees for unmodulated region. Experimental results provide the performance comparison between the discontinuous SVPWM (DSVPWM) and the traditional continuous SVPWM (CSVPWM) techniques to confirm the reduction of switching losses and output current ripple at high modulation index. The experimental results show that total average values of normalized switching losses of the DSVPWM and the CSVPWM are 7.908 and 11.174, respectively in which the proposed DSVPWM can reduce the switching losses from the conventional CSVPWM up to 29 percent.
