Average current-mode control, as shown in Figure 1, is common in continuous-conduction-mode (CCM) power factor correction (PFC). It has two loops: a voltage loop that works as an outer loop and a ...
An AC/DC power supply with input power greater than 75 W requires power factor correction (PFC) to: Take the universal AC input (90 V to 264 V) and rectify that input to a DC voltage. Maintain the ...
