In this paper, a simplified and generalized SVPWM algorithm is developed for a cascaded H bridge multilevel inverter using sampled values of reference phase voltages, which has a close similarity with Sinusoidal Pulse Width Modulation (SPWM).Abstract:
Improved dc bus utilization of voltage and its easier realization in digital domain has made Space Vector Pulse Width Modulation (SVPWM) quite popular in AC drives application. The classical Space vector pulse width modulation involves sector calculation and region estimation which results in more computational burden and complexity. A new simplified and generalized SVPWM algorithm is developed for a cascaded H bridge multilevel inverter using sampled values of reference phase voltages. The discussed method has a close similarity with Sinusoidal Pulse Width Modulation (SPWM). Implementation of the proposed SVPWM is not laborious and extension to n level is simple and straight forward. The proposed method is validated using a five level cascaded H bridge multilevel inverter driving an Induction motor.read more
