The delay line of a travelling wave tube amplifier (TWT) needs a high DC voltage. A power converter with high transformation ratio is necessary to obtain high output voltage from low input voltage. As a result, a large number of turns is necessary for secondary windings and large leakage inductane and large parasitic capacitor appear. Thus, it is usual to design resonant converter to include both leakage inductance and capacitance in the power topology. The present paper presents the design of a high voltage power supply for the delay line of a TWT using a resonant converter. All elements of the power supply (high voltage transformer, rectifier, filter and control) are designed taking high voltage and high frequency problems into account.
