Using gallium nitride (GaN) field-effect transistors (FETs) in a power supply can help boost efficiency and enable operation at higher switching frequencies, helping designers meet the strict power ...

The proposed topology is based on the integration of two flyback converters, one for each half-cycle of the grid voltage, avoiding the usual diode bridge rectifier for LED lamps drives, thus providing ...
