Latest Patents
One of his latest patents is a single-ended forward DC-to-DC converter that provides enhanced resetting for synchronous rectification. This innovative converter includes a transformer with a primary winding connected to a primary switch and a secondary winding connected to a secondary switch along with a clamping capacitor. The clamping capacitor plays a crucial role by storing magnetization energy from the secondary winding when the primary switch is turned off. This mechanism allows the transformer core to reset during the off period of the primary switch. The design utilizes MOSFETs as the primary and secondary switches, enabling an automatic turning on of the secondary switch when the primary switch is turned off. This combination of the clamping capacitor and MOSFET switches simplifies the DC-to-DC converter while eliminating undesirable characteristics such as dead time and voltage stresses on the switches. The converter is capable of synchronous rectification and zero voltage switching, marking a significant advancement in the field.
