Abstract
The leakage inductance of the isolation transformer of a single-ended DC-to-DC converter resonates with a resonant capacitor connected in series with the transformer secondary to provide substantially zero current in the switching transistor during turn-on and turn-off. The overall transistor current stress is low since it is bounded by the sum of average input current and average output current. These factors allow the converter to be operated at high frequencies for improved performance.
