Patent ID: 8493751

Claim:
A DC/DC power converter comprising: a nonisolating switching regulator that receives a DC input voltage and has a regulator DC output voltage; and a nonregulating isolating converter receiving the regulator DC output voltage and providing an isolating converter DC output voltage, the nonregulating isolating converter comprising: a primary transformer winding circuit having at least one primary winding; and a secondary transformer winding circuit having at least one secondary winding coupled to the at least one primary winding and having plural controlled rectifiers, each having a parallel uncontrolled rectifier; a voltage sensor sensing a sensed voltage on the primary side of the power converter; a current sensor sensing a sensed current on the primary side of the power converter; and control of the regulator DC output voltage based on both the sensed voltage and the sensed current without bridging an isolation barrier between the primary and secondary transformer winding circuits.
