Buck/boost conversion device and control circuit for bidirectional buck/boost converter

Abstract

A control circuit for a bidirectional buck/boost converter, comprising: a buck/boost detection unit configured to detect and output a mode of operation of the bidirectional buck/boost converter selected from buck mode and boost mode; a voltage/current regulator unit configured to receive the mode of operation output from the buck/boost detection unit and output a corresponding regulating signal based on the mode of operation; a PWM control unit configured to receive the regulating signal from the voltage/current regulator unit and output a PWM control signal based on the regulating signal; and a gate drive signal toggle unit configured to receive the PWM control signal and the mode of operation, generate and output gate drive signals for driving switching operations of a plurality of switches of the buck/boost converter based on the above. A buck/boost conversion device comprising the bidirectional buck/boost converter and the control circuit is also provided.
