摘要
近几十年来,随着功率密度的提高,DC/DC变换器软开关技术取得了很多成就。从谐振变换器、软开关-PWM变换器以及移相全桥软开关变换器三个方面对直流软开关技术进行了综述,比较了各种软开关技术的优缺点;对进一步提高软开关变换器效率的改进方法进行了展望。
In recent decades,with increasing power density,many achievements have been made in soft-switching converter technology.An overview was made on state-of-the-art of soft-switching techniques,including resonant converters,soft-switching PWM converters and full-bridge phase-shift soft-switching converters.Their advantages and disadvantages were compared.Finally,methods to improve efficiency of soft-switching converters were proposed.
