Abstract
A method to control an output voltage of a DC-DC converter, and voltage control logic operable to generate a voltage command to implement the control method, the method including sensing a voltage of a bus of an electric-drive vehicle; increasing a command voltage signal from the sensed voltage to a nominal voltage during a first time period; increasing the command voltage signal from the nominal voltage to a desired voltage during a second time period greater than the first time period; and generating a voltage output based on the command voltage signal.
