摘要：
Aiming at the voltage spike problem of the three-phase single-stage full-bridge power factor correction (PFC) converter, a suppression strategy based on passive clamp circuit was proposed. Compared with the existing voltage spike suppression strategies based on passive snubbers, the PFC converter with the proposed method has better voltage spike suppression, and the additional current stress of each switch is smaller. The operational principle of the PFC converter with the proposed passive clamp circuit as well as the mechanism of its integrated-transformer was analyzed in detail. On this basis, the key parameters of the proposed clamp circuit were analyzed, and design principle of the clamp circuit was summarized. Finally, the experiments on the existing experimental prototype of three-phase single-stage full-bridge PFC converter demonstrate the feasibility of the proposed scheme and the validity of the theoretical analysis. © 2019, Electrical Technology Press Co.
