The arrangement of the full-bridge, current-source inverter as a power supply for ozone generators providing high power factor (PF) and high electrical efficiency in a single stage is the main contribution of this paper. The corresponding design, simulation, and experimental results are presented. Also, the use of the current-fed, full-bridge resonant inverter for PF correction in ozone generation applications is discussed. The proposed power supply consists of an ac supply, a single rectifier bridge, an input inductor to the inverter, four switches, an LC parallel resonant tank, a resonant transformer, and a set of ozone generating cells. Experimental results with the proposed topology provided 96% for PF, 91% for electrical efficiency, and ozone production of 614 mgO3/min, satisfying the requirements of the standard 61000-3-2, class A.
