Modular High-Voltage Power Supplies design

Abstract

Modular High Voltage Power Supplies (HVPS) have crucial advantages over one-module HVPS. The article is devoted to a new patented HVPS technology. The new method of HV generation creates new possibilities for advanced HVPS performance. New design makes HVPS much smaller and lighter. HVPS reliability is enhanced. Manufacturing cost is close to the cost of conventional HVPS. The HVPS consists of a number of modules connected in series. Each module generates DC high voltage. Output voltages from these modules are connected so that the HVPS output voltage is the sum of the modules' voltages. A LV rectifier, filter, DC-to-AC high frequency converter are on the LV parts together with magnetic cores and primary winding of the HV transformer. The secondary windings of the HV transformer with HV rectifiers, HV capacitors and HV divider belong to the high voltage part of a module. This modular HVPS is capable of generating outputs in many different waveforms. HVPS's components are located on a pair of high voltage cards and a pair of low voltage cards on which high and low voltage components are respectfully mounted. Mounted between the cards are the transformers, each of which is coupled to a full bridge rectifier and outputs of the rectifiers connected so that an output voltage produced by each transformer/rectifier pair is summed to produce a total output voltage for the HVPS. The components on the high voltage cards are both physically and electrically isolated from the components on the low voltage cards.
