Patent number: 6278621Abstract: A single ended forward DC-to-DC converter includes a transformer having a. primary winding electrically connected to a primary switch and a secondary winding electrically connected to a secondary switch and a clamping capacitor. The clamping capacitor stores the magnetization energy from the secondary winding when the primary switch is turned off, thus causing the transformer core to be reset during the period that the primary switch remains off. The converter can use mosfets as the primary and secondary switches, such that a change in the voltage at the secondary winding of the transformer, due to the turning off of the primary switch, results in an automatic turning on of the secondary switch. The combination of the clamping capacitor and the mosfet switches increases the simplicity of the DC-to-DC converter while eliminating undesirable characteristics such as dead time and voltage stresses on the switches.Type: GrantFiled: June 6, 2000Date of Patent: August 21, 2001Assignee: International Power Devices, Inc.Inventors: Gang Xia, Fei Ma
