Control Strategy of High-frequency AC-AC Converters for Plasma Generators Considering Improvement of Output Power Quality

Hyo Min Ahn et 7 al.

Jan 1, 2018 in 2018 21st International Conference on Electrical Machines and Systems
In this paper, a control strategy of a 2-stage AC-AC converter for a plasma generator consisting of an AC-DC PWM converter and a high-frequency phase-shift full-bridge DC-AC inverter is proposed. In case of previous control methods of this configuration, the output power quality in the light-load region is not seriously considered. Therefore, the control method to minimize degradation of the outpu...
