To produce such high voltages from a low battery voltage, designers typically use switch-mode dc/dc converters... B Travis - 《Electrical Design News》 被引量: 0发表: 2004年 直流微网混合式零电压开关直流断路器 Zero-voltage- switch hybrid DC switch for DC microgrid[J]. High Voltage Engi-...
44、-DC Converters,As the switch is turned on in mode l, the diode is reverse biased and the current flows through inductor into the voltage sink. After a time , the switch is turned off. The inductor current then freewheels through the diode as shown in the circuit of mode 2. The ...
峰值电流模CPM可近似建模为iL(t)=ic(t). 将diode/switch建模为一个current source,其值为ic, 或者power sink or source (取决于topology). 通过Perturbation and linearization可得小信号模型. 当然也可以用Chapter 7的方法直接小信号化简. 峰值电流模近似建模显示line-to-output and control-to-output的传输函数少...
对于电力电子可用的device就是电阻, 电容, switch, 电感(或者变压器). 电感可能没办法集成到芯片. 一个典型的buck converter架构如下 电力电子的类型主要分为DC-DC (buck, boost等), DC-AC (inverter), AC-DC (rectifier), AC-AC. 其中DC-DC应用最广, 后面的篇幅也主要讲DC-DC. Chapter 2 Principles of ...
