Abstract
A converter comprises a bridge and a resonant tank coupled between the bridge and an isolation transformer. The converter is configured such that the converter operates at a first constant-gain resonant frequency during a normal operation condition wherein a voltage gain of the converter is essentially insensitive to an output load change and the converter operates at a minimum-gain damping frequency during an abnormal operation condition wherein a voltage gain of the converter is approximately equal to zero.
