Abstract
A simplified control strategy for threephase
PWM rectifier without measuring the supply
voltage is presented. Beside simplicity, the proposed control algorithm is robust, inexpensive, and can be used for unity or variable power factor operation. This paper
describes the proposed control strategy and its implementation with the help of a low cost Intel 80C196KC microcontroller and three-phase bridge inverter using IGBT transistors. The experimental results are presented to prove the near sinusoidal and low harmonic content of the ac-line current.
