Abstract
The improved DC-DC converter apparatus includes a primary side circuit and a secondary side circuit that is galvanically isolated from the primary. The primary side induces a voltage in the secondary side that provides an output voltage for driving POLs. A flux-control device measures the transformer primary side flux to control the primary side duty cycle, thereby loosely regulating the output voltage of the secondary side circuit.
