DC/DC converter of the 'forward' type with zero-current switching and two-way current operation

摘要

DC/DC converter comprising a transformer whose primary L1 is coupled to a source +E by a MOS transistor T1. A diode D1 and a second MOS transistor T2 in parallel are connected in series with a capacitor C and the secondary L2. The second MOS transistor T2 is controlled directly by the voltage across the terminals of the capacitor C. This converter, of the "forward" type, switches at zero current whilst being practically able to operate at a constant frequency. IMAGE
