采用嵌入升压单元的双移相控制宽增益范围隔离升降压变换器
Dual-phase-shifted Controlled Isolated Buck-Boost Converter With Wide Voltage-gain Employing Built-in Boost Cell
摘要
Abstract
A dual-phase-shifted controlled isolated Buck- Boost converter with wide voltage-gain along with its control strategy was proposed in this paper. By adding boost switches to the conventional voltage- doubler diode-rectifier, the converter can operate in Buck/ Boost modes; with dual-phase-shift modulation, soft- switching of active switches and naturally turn-off without reverse recovery of diodes can be realized in a wide range; leakage inductance of transformer is utilized for power transfer. The voltage stress of primary-side and secondary-side switches are clamped to input and output voltages which are much lower. The operation principle and steady-state characteristics were analyzed in detail and verified with experimental results.关键词
