| Abstract: | Continous current mode(CCM) Boost power factor correction(PFC) has been widely used because of its high input power factor and simple control.But it suffers from efficiency decrease under the light load or the low in-put voltage work condition.A novel enabling window control is proposed to improve the efficiency of Boost PFC,espe-cially under the light load or the low input voltage work condition.To improve the efficiency,lower switching frequen-cy is used in the selected window area to reduce the switching... |
