The present disclosure provides a converter including a primary stage having a plurality of primary stage switches, a secondary stage having a plurality of secondary stage switches and a capacitor, and a controller that isolates the secondary stage from a second battery, and that controls switching of the plurality of primary stage switches and the plurality of secondary stage switches to provide a plurality of bursts of energy from a first battery to the capacitor to pre-charge the capacitor to a threshold voltage, wherein after an initial burst of the plurality of bursts having an initial duration, a subsequent burst of the plurality of bursts provided has a duration equal to a duration of a preceding burst plus a time period based on a voltage of the first battery.

DC-to-DC converter and method for controlling same

A converter module is provided with a first power delivery circuit, a second power delivery circuit, and a controller. The first power delivery circuit supplies current from a first direct current (DC) source to a resonant stage in a first direction. The first power delivery circuit comprises at least two first switches. The second power delivery circuit supplies the current from the first DC source to the resonant stage in a second direction, opposite the first direction. The controller includes memory, and a processor that is programmed to: enable the first power delivery circuit and the second power delivery circuit alternately to provide power as a periodic waveform to the resonant stage; and disable the at least two first switches individually in a sequence to generate a phase shift in the periodic waveform and to disable the first power delivery circuit.
