Abstract: An efficient control method for an isolated multilevel DC/DC resonant converter achieves a wide output voltage range with a narrow device switching frequency range, relative to the output voltage range and the device switching frequency range of the prior art. At any given time, a control circuit selects one of three different modulation schemes to operate the primary-side switching devices of the resonant converter based on at least one of output voltage, output current, input signal, and one or more external control signals. Together with a selected device switching frequency, the three modulation schemes generate different voltage waveforms to a primary-side transformer, which are coupled to the secondary-side to provide different output voltages.

Abstract: All designs have features that prevent the running boards from over deploying and stowing. This ensures the mechanism does not exceed the design range of motion and prevents any excess forces on the system or vehicle. All designs use kinematic locks to prevent back driving in stowed and deployed positions, which allows more efficient gearboxes to be used.

Abstract: A novel phase-shift based modulation strategy is disclosed that enables a DC-DC converter to operate with zero voltage-switching (ZVS) across wide voltage and power range. The converter operates at a fixed fundamental frequency, with the output current controlled based on an amount of phase shift of the fundamental component at the output of an inverter portion of the converter. To achieve soft switching a rectifier portion of the converter is controlled to phase shift the fundamental component of the rectifier voltage observed at a rectifier reference terminal. More specifically, by requiring a phase shift of the voltage at the rectifier terminal relative to the output voltage of the inverter, the inverter current is such that ZVS is achieved. A converter and method are provided to implement DC-DC conversion with soft switching.
