Reactive power handling with series-resonant converters

摘要

A description is given of a series-resonant reactive power compensator based on a series-resonant converter topology. The compensator delivers high-quality sinusoidal waveforms, while it preserves the advantages of resonant converters, such as low switching losses and low component stress, improved reliability, low electromagnetic interference (EMI), and low size and weight of components. The topology an associated switching schemes are derived. Simulation results are presented and measured waveforms are shown for a 1-kVA compensator.
