In this paper, a single-phase PWM boost rectifier operating at a controlled power factor has been simulated and implemented. The power circuit under investigation is a single-phase full bridge converter using IGBT transistors. The control algorithm provides the regulation of the output DC voltage as well as the control of supply current power factor. In addition, the proposed control strategy is implemented using a low-cost microcontroller Intel 80196. The experimental prototype offers several advantages such as; simplified control system, sinusoidal ac line current that satisfies the recently published harmonic current standard IEC 1000-3-2 Class D.
