Unity Power Factor Control by Pwm Rectifier
Abstract This paper analyzes the principle of PWM rectifier and presents a unity power factor control method of PWM rectifier. Controller used double closed-loop PI control, which inner uses three-phase input current control method controlled by unity power factor and outer controls the output DC voltage of rectifier. Voltage phase detection methods which proposed could eliminate the affection ...

متن کاملControl of Transformerless Uninterrupted Power Supply for Unity Power Factor and Sinusoidal Inductor Currents
This paper discusses the design of controller for transformerless uninterruptible power supply (UPS), with simultaneous ac and dc loading. The objective of the design is to maintain good regulation of the ac and dc voltages and sinusoidal inductor currents simultaneously. The volt-second balance across the output filter inductor is used to maintain the current in sinusoidal form which is the un...
متن کاملA Predictive Control Strategy for Power Factor Correction
Harmonic pollution and low power factor in power systems caused by power converters have been a great concern. To overcome these problems several converter topologies and control schemes have been proposed in recent years. This paper is proposed to study the control techniques for such converters to improve the Power Factor (PF) and reduce total harmonic distortion (THD) in the input current wi...
