DC-DC power converter control techniques

摘要

Techniques for an isolated DC-DC converter are provided. In an example, a method of operating an isolated DC-DC converter can include inducing a first, primary current flow in primary windings of a first transformer and a second transformer during a first interval, inducing a second, primary current flow in the primary windings during a second interval, freewheeling current of the primary windings via a ground connection of the primary windings during transitions between the first interval and the second interval, and repeatedly alternating between the first interval and the second interval to generate a single DC output voltage using a secondary winding of the first transformer and a secondary winding of the second transformer.
