A dual power switching system includes a first STS, a second STS, an inductive device, and a controller. The first STS is electrically coupled to a main power source, and the second STS is electrically coupled to a backup power source. When detecting that the main power source is abnormal, the controller detects a residual magnetic flux of the inductive device and calculates a magnetic flux difference between the predicted magnetic flux and the residual magnetic flux. When determining that an absolute value of the magnetic flux difference is less than or equal to a magnetic flux deviation value, the controller determines whether the output power meets a forced commutation condition. When determining that the output power meets the forced commutation condition, the controller turns on the second STS so that the first STS is forcibly turned off by the backup power source through the second STS.

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.
