Higher Order Series Resonant Dc-Dc Converter For High Voltage Applications

The conventional series resonant High Voltage (HV) DC-DC converter power supply is able to absorb the leakage inductance of the HV transformer, provides lower component stress and prevents the HV transformer from being saturated but poses poor controllability at light load and lower efficiency. To o...
