Implementaion of An Audio-Glass Amplifier by Controlling the Current of PWM Inverter

PWM 인버터 전류제어에 의한 오디오급 엠프 구현

This paper presents a simple high power audio class amplifier which is controlled by a new current control switching method. Although this class D amplifier has an only one current control loop with the proposed switching method, a good performance can be obtained. And a novel switching strategy for driving stereo signal amplifier circuit with three phase full bridge is discussed also. With the simulation and experimental results, usefulness of the proposed amplifier is confirmed.
