Abstract
A power converter providing required hold up for a primary converter, particularly a cycloconverter, without the required hold up capacity by an auxiliary converter including storage capacitors having the requisite capacity. The auxiliary converter may be isolated from the primary converter during normal operation and switched in during power supply discontinuities. The storage capacitors may be charged via a voltage step up circuit to achieve improved charge utilization. The storage capacitors may be charged via a charge path independent of the auxiliary converter output path so that the storage capacitor charging rate may be set independently.
