Latest Patents

Ming-Hsuan Lee holds a patent for "Flyback power converters having a high side driving circuit." This invention features a dual-switch flyback power converter that includes a control circuit to generate a switching signal. The high-side driving circuit incorporates a pulse generation circuit that produces both a pulse-on signal and a pulse-off signal to control two transistors in response to the switching signal. These transistors provide a level-shift-on signal and a level-shift-off signal to a comparison circuit, enabling or disabling a high-side driving signal. Notably, this design eliminates the need for a charge pump circuit to power the high-side driving circuit, utilizing a floating winding of a transformer instead. This innovation reduces the cost of the dual-switch flyback power converter while ensuring sufficient high-side driving capability.
