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 power components/modules such as MOSFET, IGBT, or GTOs to realize four quadrant power conversion so as to perform as grid-connected inverters, active power filters, power factor corrected rectifiers, flexible ac transmission system components, and etc. Due to its fast speed, simplicity, stability, and universal adaptability, one-cycle control promises unmatched performance, cost effectiveness, and robustness. This paper shows four basic building blocks for grid-connected applications, countless combinations of which can be configured to meet the power processing needs of the industry, transportation, defense, and power systems.
