Abstract
This paper presents a novel interleaved boost integrated LC series resonant converter with two output rectification modes, which are voltage-doubler rectifier mode and voltage-quadrupler rectifier mode with constant output voltage for wide input voltage range applications. Due to the symmetrical configuration of the rectifier, the voltage stress of switches and diodes on the secondary side are only half of the output voltage. With the proposed pulse frequency modulation, the maximum magnetic flux density <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">B<sub>m</sub></i> of high frequency transformer is only related with the resonant frequency rather than the switching frequency. Hence, the transformer can be frequency-free designed. The zero-voltage-switching of the primary switches and zero-current-switching of the secondary switches and diodes are achieved, respectively. Moreover, the design procedure for some key parameters is presented. Finally, a 470 W prototype with a switching frequency range from 50 kHz to 140 kHz is built to verify the operation principles of the proposed converter and modulation.
