Space Vector Pulse Width Amplitude Modulation for Boost Voltage Source Inverter

This paper proposes a space vector pulse width amplitude modulation (SVPWAM) method for a boost voltage source inverter. For a VSI, the switching loss is reduced when compared to a conventional sinusoidal pulse width modulation (SPWM) method. The output harmonic distortion of SVPWAM is lower than that of the SPWM, by using only one-third of the switching frequency compared to the latter one. As a result, it is feasible to use SVPWAM to make the boost inverter suitable for applications that needs high power density, high efficiency and low cost. The application includes DC power source utilization, power grid, induction heating and electric vehicle motor drive.
