Abstract
Embodiments of the present disclosure provide an active equalizer circuit, a battery management system, and a power supply system. The active equalizer circuit comprises a plurality of switching transistors, a driving transformer, a multi-port converter, a buck converter, and a microcontroller. Each of the switching transistors is coupled to a battery cell in the series battery pack on a one-to-one basis. The multi-port converter comprises an equalizing transformer and a bridge converter. The microcontroller is configured to output a first control signal to the buck converter, to facilitate the buck converter to transform an output voltage of the series battery pack and output the transformed output voltage to the bridge converter, and output a second control signal to the bridge converter, to control an operation state of the bridge converter.
