用于消除半桥D类音频放大器电源泵升效应的软开关对称双极性输出直流变压器

A soft switching symmetric bipolar outputs dc-transformer (DCX) for eliminating power supply pumping of half-bridge class-D audio amplifiers is proposed in this paper. Compared with the traditional unidirectional front-end dc-dc converter in the half-bridge class-D audio amplifier, output capacitances of the proposed DCX and voltage stress of the half-bridge class-D audio amplifier are significant...
