Abstract :
A soft-switching type multiple-chip power device (M-Power) has been presented. The power supply that applies M-Power satisfies energy saving, low-EMI noise and low-input current distortion requirements while being compact. In this paper, the features of this power supply are introduced. High efficiency and low-EMI noise are achieved by applying a novel soft-switching circuit, and low-input current distortion is achieved by using a novel one converter-type power factor correction circuit. Low-dissipation losses while in standby mode are achieved using a standby mode control that operates at a lower switching frequency than that of normal mode.
