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. 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.

Apparatus for delay compensation for a power conversion device

In at least one embodiment, a system comprising a first circuit and a second circuit is provided. The first circuit includes a first filter filtering a first input signal and generating a first filtered output signal. The first circuit includes a first comparator comparing the first filtered output signal to a first threshold value and providing a first output signal indicative of a failure condition to one or more first processors. The second circuit includes a second filter filtering the first input signal and generating a second filtered output signal to filter the first input signal in less time than the first filter filtering the first input signal. The second circuit includes a second comparator comparing the second filtered output signal to a second threshold value and providing a second output signal indicative of the failure condition to one or more second processors.

Apparatus for providing parallel filtering

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.
