Abstract: A high power factor (HPF) electronic ballast, with low switching losses, single power processing stage, that provides high frequency voltage to the fluorescent lamps is presented. HPF is achieved by using a nonconventional boost converter operating in critical conduction mode.

   A new power-factor-correction controller for the CSPRR

Abstract: This paper presents a simple control architecture for the high-power-factor current-source parallel resonant rectifier, based on the quasi-steady-state approach. In relation to traditional multiplier approach, the proposed controller substitutes the multiplier circuit and the input-voltage sensor by a multiplexer and low-pass filter, simplifying the control circuitry. Moreover, the comparison of the line-current distortion of these controllers shows similar performance.

Abstract: A low-cost high-frequency power supply family for ozone generation is presented in this paper. Firstly, the results obtained from the ozone reactor tested at high frequency are presented, and a new model for its high frequency behavior is proposed. Secondly, the basic power supply stage is presented and analyzed, obtaining some important characteristics that allow the correct design of this power converter. Around the proposed converter several models of power supplies able to drive the ozone reactor from different ac and dc input voltages have been developed. Simulation and experimental results are also provided to evaluate the possibilities of the proposed converter.
