Abstract
This paper introduces a simple space vector PWM algorithm for a cascaded multilevel inverter. The scheme determines the location of the reference vector easily. It uses space state equation to get the value of vector. A cascaded thirteen-level inverter is used to explain the scheme. The scheme can be easily extended to n-level inverter. It is applicable to cascaded multilevel high voltage inverter and cascaded active compensation device. The result of simulation verifies that the scheme is useful in improving utilization of the direct current (dc) link voltage and reducing THD.
