A simplified space vector pulse width modulation algorithm for five level diode clamping inverter

Abstract

A simplified space vector pulse with modulation (SVPWM) method for the five level diode clamping voltage source inverter is presented. The space vector diagram of the five level inverter is simplified into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Thus, the algorithm of five level SVPWM becomes very similar to that of conventional two level inverter SVPWM. This method can be extended easily to multi-level inverters above five level
