Abstract
Various disclosed embodiments include illustrative controller modules, direct current (DC) fast charging devices, and methods. In an illustrative embodiment, a controller module for a DC-DC converter includes a controller and computer-readable media configured to store computer-executable instructions configured to cause the controller to: receive an input voltage, an output voltage, and a requested power value. The computer-executable instructions are configured to cause the controller to: determine primary and secondary side inter-bridge phase shifts responsive to the requested power value, the input voltage, and the output voltage; determine an effective phase shift value responsive to the requested power value, the input voltage, the output voltage, and the primary side inter-bridge phase shift; generate control signals for switches of the DC-DC converter responsive to the primary side inter-bridge phase shift, the secondary side inter-bridge phase shift, and the effective phase shift value; and output the generated control signals.
