一个口诀掌握|电源CC与CV模式的跳转规律 CV(Constant Voltage):恒压模式(CV mode)定电压模式(也叫恒压)是指负载的电流值在额定范围内变化,而直流电源供应器的输出电压保持稳定的工作模式, 即当负载改变而导致输 - 安泰小课堂于20241121发布在抖音,已经收获了26.0
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...

This paper describes a completely digitally controlled bidirectional multi-phase dc-dc converter capable to operate in buck-and boost mode. All necessary tasks are performed within a FPGA circuitry. The voltage and current mode control is based on a voltage to frequency converter (u/f), also cal...
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 ...
