一种基于改进半桥变换器结合APWM与PFM控制的均衡器

A charge equalizer with a combination of asymmetrical pulse width modulation and pulse frequency modulation control based on a modified half-bridge converter for electric vehicles is proposed in this paper. The reliability of the charge equalizer can be improved because the split capacitors are not required and the soft switching of power switches can be achieved by the proposed control. In additi...
