Abstract
The higher precision and low noise in output voltage and current has been required in some applications i.e. audio-video equipment, medical equipment and so on. In this paper, a new power converter which realizes low noise output with high efficiency is proposed. In the proposed converter, a hybrid filter is inserted to the output of a PWM inverter. The hybrid filter is composed of LC filter and a power amplifier. The amplifier is inserted in series to the filter capacitor to improve the LC filter. Noise suppression effects of the proposal circuit are verified by simulations and experiments.
