摘要:Based on the requirements of power processing unit(PPU), this paper proposes a converter suitable for its wide input and wide output voltage range applications. The first stage adopts a four-switch Buck-Boost converter, which operates in two-mode state and can meet the request of wide input and wide output voltage range. At the same time, the interleaved parallel technology is used to reduce the inductor volume, so that the power density can be increased. The circuit topology of the second stage employs an LLC resonant converter. The LLC resonant converter operates in fixed frequency mode to obtain a stable voltage transfer ratio, which is similar to the DC transformer; the LLC resonant converter can achieve zero voltage turn-on of the primary side switches and zero current turn-off of the secondary side diodes, which can contribute to the increase of efficiency. © 2019 IEEE.
