摘要：

A soft-switching scheme for the PWM boost converter is newly proposed to obtain the desirable features of both the conventional PWM boost and resonant converters such as ease of control, reduced switching losses and stresses, and low EMI. In order to achieve the soft-switching action, the proposed scheme employs an auxiliary circuit, which is added to the conventional boost converter and used to achieve soft-switching for both the main switch and the output diode while not incurring any additional losses due to the auxiliary circuit itself. The basic operations, in this paper, are discussed and design guidelines are presented. Through a 100 KHz, 60 W prototype, the usefulness of the proposed scheme is verified.
