OPERATION IMPROVEMENT OF A HIGH-VOLTAGE SERIES RESONANT SUPPLY

This paper describes a method to eliminate the effects induced by the high voltage parasitic elements in a static resonant supply. This is done not by modifying the converter structure but by redefining the high voltage transformer structure. A high voltage DC-DC converter has been designed and a model of the high voltage transformer established. The influence of the transformer parasitic elements on the structure operation is validated with the help of a simulation. A method is then proposed to eliminate the effects induced by the high voltage transformer parasitic capacitance. This method has a technical advantage: it is easier to put it into operation than to reduce the parasitic capacitance.
