Single-Switch Power Supply based on the Class E Shunt Amplifier for Ozone Generators

In this paper a single-switch power supply based on the shunt class E amplifier is presented. A simple and easy method to analyze the complete system is proposed and one way to provide compensation to parameter's variation of the ozone generator and to reduce the size of the resonant inductor is proposed and studied too. The selected topology offers a low-cost and high-power density source that efficiently supplied the system. Experimental results are congruent with the specifications and a high ozone concentration is obtained.
