Sliding Mode Control Based on Observation of line side PWM Rectifier Voltage

Pulse width modulation (PWM) rectifiers are among the best solutions for improving the electrical power transfer quality from a source to a receiver. In fact, some authors have presented several methods for controlling the three-phase PWM rectifier and eliminating total harmonic distortion to achieve an uncontaminated system operating within a unit power factor. This article focuses on the sliding mode method, which is based on data from two or three line current sensors and a DC link voltage sensor, as well as the development of the most modern network voltage controllers, which include a sliding mode regulator for the system. The simulation results demonstrate the viability and reliability of the observer's sliding mode methodology in a transient and stable state with a quasi-sinusoidal low total harmonic distortion (THD) line current source and a good maintenance of the reference voltage on the same day, in the DC side of the PWM rectifier, in accordance with standards.
