One-cycle control and its applications in power quality control and renewable power generation

One-cycle control is a universal method to control single or three-phase MOSFET, IGBT, or GTO power modules to realize four quadrant power converters that are capable of serving as grid-connected inverters, active power filters, power factor corrected rectifiers, flexible ac transmission system components, etc. Due to its fast speed, simplicity, stability, and universal adaptability, one-cycle control promises unmatched performance, lower cost, and high reliability. This paper shows some representative examples. Countless combinations of those can be made to meet the power processing needs of the industry, transportation, defense, and power systems.
