The Application of Inverted Excitation Conversion Technique High Voltage DC Supply

In this paper,the working principle,feutures and voltage clamper circuit of the single-end inverted excitation convertor are introduced,the controlling characteristic and ripple of the high voltage DC Supply by applying the inverted excitation conversion technique are analyzed. The experiments show that the high Voltahe DC suppy using the iinverted excitation conversion techique has good selflimit current and self-limit voltage characteristics. These can effectively protect the power electronic comPOnents in the case of abnormal phanomena such as overloading and short-circuit.
