Abstract :
A high performance reactive power compensator is presented and analyzed. The volt-ampere reactive (VAr) compensator consists of a three-phase current-regulated pulse width modulated voltage-source inverter connected to a self-controlled DC bus. Reactive power compensation is achieved by forcing the inverter output current to follow a reactive sinusoidal reference waveform at a constant switching frequency. The scheme is discussed in terms of principles of operation, power and control system design, and the analysis under transient operating conditions. Simulated results obtained with the PSpice simulation software package for steady-state and transient operating conditions are presented.<>
