Abstract

In accordance with one embodiment, a system and method of controlling a direct current to direct current converter that comprises a primary full bridge coupled to a secondary full bridge via a transformer. After the start-up time period, an electronic data processor controls the converter to operate efficiently in a first control mode, a second control mode, or a third control mode, wherein the first control mode comprises a phase shift mode, the second control mode comprises a triangular waveform control mode and wherein the third control mode comprises a trapezoidal waveform control mode. The electronic data processor determines a maximum target power range and a transition power level threshold for each one of the control modes.
