Online Load Power Factor Angle Estimation and its Application in a Current Sensor-less Dead-time Distortion Compensation Technique in Single-phase PWM VSI with Lagging Load

Abstract: Dead-time distortion is a major issue in PWM VSI, which results in a deviation in the profile of the inverter output voltage and reduction in the amplitude of its fundamental component.
