Voltage Mode就是三角波幅度倒数, Current Mode是电压和电流的综合),Kf和Kr是考虑了Vg和Vo的扰动影响, 其值很小, 一般忽略没有大的影响. Hv是电压反馈环, Hi是电流采样系数, 负号表示负反馈. 如果是采样电阻的CIC(Current Injection Control)法, Hi就是采样电阻,如果是电感电压的SCM(Standard Current Mode)法...
A switched mode converter is disclosed that includes both voltage mode and current mode control. The switched mode converter also includes mode logic for switching between a voltage mode and a current mode. The converter includes current sensing circuitry for sensing the switcher current on the prima...
After that, a digital application of current-mode control is introduced. High-resolution digital pulse-width modulator (DPWM) is considered to be indispensable for minimizing the possibility of unpredicted limit-cycle oscillations, but results in high cost, especially in the application of voltage ...
