Abstract :
A full bridge power converter that utilizes one-cycle control is proposed for audio power amplification. Experimental results demonstrate that the new power amplifier overcomes the nonlinearity of the switching power converter and achieves high power ripple rejection and low output signal distortion. It is suitable for high efficiency and high fidelity audio power amplification applications
