摘要

提出了一种工作在恒频、宽线性的零电压开关DC/DC变换器。ZVS操作实现了主开关和次级整流二极管，以减少开关应力和损耗。该变换器具有器件和元件的低伏安额定值，恒定的开关频率工作，以及几乎线性和负载无关的直流转换比特性。电压和电流应力很低，并且总是分别局限于电源电压和输出电流。

A soft switching constant frequency PWM DC/DC converter with low switch stress and wide linearity

A zero-voltage-switching (ZVS) DC/DC converter which operates on constant frequency and has wide linearity is proposed. The ZVS operations are achieved for the primary switches and for the secondary rectifier diodes to reduce the switch stresses and losses. The converter has low volt-ampere ratings for the devices and components, constant switching frequency operation, and almost linear and load-independent DC conversion-ratio characteristics. The voltage and current stresses are low and are always limited to the supply voltage and the output current, respectively.<>
