Abstract
Faults in the secondary-loop of a trans-inductor voltage regulator (TLVR) are detected. Each power stage of the TLVR is connected to a primary winding of a respective transformer in the TLVR. The secondary windings of the transformers and a compensation inductor form a secondary-loop. A phase controller in the TLVR operates to both drive a first power stage to an ON state and to place a second power stage in an OFF state in a first duration. In the first duration, if the first power stage draws a current less than a maximum threshold and if a voltage at the switching node of the second power stage is negative, the phase controller determines that no faults exist in the series secondary circuit. Otherwise, the phase controller determines that one or more faults exist in the series secondary circuit.
