WebMar 14, 2015 · R. Ridley’s current mode model [3] is the most popular one used by the power supply industry for both peak current mode and valley current mode controls. Most recently, Jian Li developed a more intuitive circuit model [4] for current mode control, which can also be used for other current mode control methods. WebJul 1, 2004 · A peak current-mode power supply is subject to subharmonic oscillations if two conditions are met: the converter operates in the continuous conduction mode (CCM) and …
