WebJul 30, 2014 · The classic small-signal model for current-mode and voltage-mode control methods to approximate the system as time-invariant cannot be applied here. This is why the transfer function for COT control cannot be explicitly derived as other control methods. In the literature, the describing function method is employed to model the COT control. WebVoltage Mode Advantages Voltage mode control, where the output voltage is the control endpoint, is conceptually easier to understand than current mode control. Sensing voltages is easy. Typically a resistor divider scales the output voltage to a value that is read by an ADC (Analog to Digital Converter), or is presented to an analog comparator.
WebIn continuous conduction mode with a steady output current requirement, the COT control operates at an approximately fixed frequency. However, during a load-step transient …
WebThe converter has advantages that a condition that a traditional COT control system adopts a constant level to carry out comparison is avoided; through sampling a voltage of a SW terminal, the...
