Abstract
This paper presents the analysis and design of a single-phase
single-stage high-power-factor AC/DC converter employing a
series-parallel resonant topology operating in self-sustained
oscillating mode. A control approach is proposed to achieve low total
harmonic distortion of the input current. This approach does not require
sensing of the input current. In addition, the inverter output current
is limited during transients, and the converter operates with zero
voltage switching for all operating conditions including open and short
circuit. The performance of the proposed scheme is verified
experimentally on a 500 W prototype
