Abstract
In this paper, the implementation of 380Vdc to 160kVdc high voltage DC/DC converter is described. The converter was designed based on the parallel loaded resonant converter(PLRC) topology and the parallel-charged symmetrical Cockcroft-Walton voltage multiplier(CWVM). Also, the gate driver was designed for high efficiency operation of PLRC over wide load range. In addition, the high voltage transformer was designed to satisfy the voltage gain, high voltage insulation and required leakage inductance and stray capacitance which are used as resonant inductance and resonant capacitance of the PLRC. The converter has remarkable characteristics such as compact size while considering of high voltage insulation, low output voltage ripple, and long-term stable operation. The converter was verified through PSPICE simulation and experiment. Through simulation, the output of the designed converter was verified, and the loss improvement of the converter switch was analyzed and the output voltage ripple was verified. Finally, the experiment with resistor load was conducted and it was verified that the converter outputs 160kV 6mA.Keywords
