An Impression on Over Modulation Strategy in Inverter

Abstract

Energy production has continuously now become center of attraction as the global energy problem has become more significant. The Pulse Width Modulation (PWM) inverter's creation and application are critical to renewable energy technologies. Furthermore, one of the most essential concerns for PWM Inverters is Over Modulation (OM) performance. OM technology improves the primary voltage and current, reduces device variable reaction time, & increases the normal operating zone.The harmonic current issue, the difficulty of the overmodulation approach, and the seamless transition between linear and overmodulation areas are all emphasised as important issues with the overmodulation strategy.The merits and downsides of common overmodulation methods are contrasted and explained in this paper.
