Claim Text:
1. A method, comprising: determining, at a controller of an electrified vehicle (EV), the controller including one or more processors, a required output current for a DC-DC converter based on a secondary voltage of a secondary battery system of the EV, the DC-DC converter being configured to convert a primary voltage from a primary battery system of the EV to the secondary voltage; determining, at the controller, a switching frequency for the DC-DC converter that causes the DC-DC converter to output the required output current; determining, at the controller, turn-on and turn-off delays of the DC-DC converter based on the required output current and the switching frequency using one or more look-up tables; and controlling, by the controller, the DC-DC converter based on the turn-on and turn-off delays.
