Abstract: In at least one embodiment, a system is provided. The system includes a first bridge circuit, at least one transformer, a second bridge circuit, and at least one controller. The first bridge circuit includes a first plurality of switches that receives a first voltage and provides a second voltage. The transformer provides a third voltage based on the second voltage. The second bridge circuit includes a second plurality of switches that provides a fourth voltage. The controller is programmed to selectively activate at least one of the first plurality of switches and at least one of the second plurality of switches based on a predetermined modulation scheme, wherein the predetermined modulation scheme. The predetermined modulation scheme is based on at least a number of turns of the transformer, the predetermined modulation scheme minimizing a delay in selectively activating the first plurality of switches and the second plurality of switches.

Abstract: A system includes a power source, a capacitor, a precharge circuit, and/or a controller, in some configurations. The capacitor may be electrically connected to the power source. The precharge circuit may be electrically connected between the power source and the capacitor. The precharge circuit may include a switch connected in parallel with a resistor. The controller may be electrically connected to the power source and the precharge circuit. The controller may conduct a first precharging of the capacitor to a first voltage via the resistor. The controller may conduct a second precharging of the capacitor from the first voltage to a second voltage via the switch.

Abstract: 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.
