DC/DC变换是将可变的直流电压变换成固定的直流电压,也称为直流斩波。斩波器的工作方式有两种,一是脉宽调制方式Ts不变,改变ton(通用),二是频率调制(
(1)Buck电路——降压斩波器,其输出平均电压U0小于输入电压Ui,极性相同。
(2)Boost电路——升压斩波器,其输出平均电压U0大于输入电压Ui,极性相同。
(3)Buck-Boost电路——降压或升压斩波器,其输出平均电压U0大于或小于输入电压Ui,极性相反,电感传输。
(4)Cuk电路——降压或升压斩波器,其输出平均电压U0大于或小于输入电压Ui,极性相反,电容传输。还有Sepic、Zeta电路。
上述为非隔离型DC-DC变换器电路,隔离型DC-DC变换器有正激电路、反激电路、半桥电路、全桥电路、推挽电路。
当今软开关技术使得DC/DC发生了质的飞跃,美国VICOR公司设计制造的多种ECI软开关DC/DC变换器,其*大输出功率有300W、600W、800W等,相应的功率密度为(6.2、10、17)W/cm3,效率为(80~90)%。日本TDK-Lambda公司*新推出的一种采用软开关技术的高频开关电源模块RM系列,其开关频率为(200~300)kHz,功率密度已达到27W/cm3,采用同步整流器(MOSFET代替肖特基二极管),使整个电路效率提高到90%。
