Latest Patents
Ming L Chen holds a patent for a "DC-To-DC converter with secondary flyback core reset." This invention introduces a secondary flyback core reset (SFCR) scheme for single-ended forward DC-to-DC converters. The design utilizes the transformer secondary magnetizing inductor and a parasitic reset capacitance of the output forward rectifier diode to form a secondary flyback reset circuit. This circuit effectively resets the magnetic flux built up through the primary winding when the main switch is turned off, initiating a half resonant cycle that optimizes the transformer reset process. With careful design of the reset time, the maximum duty cycle of the main switch can exceed 50%, while still utilizing the core's B-H loop characteristics for improved power density and reduced switching currents.
