Title: Coupling inductor dc-dc power converter
Inventor: ANDREW FERENCZ
IPC: H01F30/10
Filed: 2018-09-04
Abstract: To provide a DC-DC power converter having reduced output current ripples and avoiding resonant energy storage.SOLUTION: The percentage of a transformer leg flux is determined by a reluctance ratio between an inductor leg 110C and a "non-winding" leg 110A. The ratio determines relative voltage induced by a varying flux across both ends of a transformer secondary winding and an inductor winding and, therefore, determines net voltage applied across both ends of an inductor. The net voltage applied across both ends of the inductor determines how much inductor current varies and, as a result, determines ripple current in an output inductor. During the remaining reset or circulator part of a cycle in a state in which a secondary side circulator switch 108 is actuated and negative reset capacitor voltage is applied across both ends of a primary winding, a polarity reverse to that of net primary winding voltage decreases current passing through the primary of the transformer to increase a magnetic flux.SELECTED DRAWING: Figure 1
