Description

technical field [0001] The invention relates to the technical field of transformer rectification and voltage doubling, in particular to a rectification and voltage doubling component and an X-ray high-voltage generator. Background technique [0002] With the rapid development of the domestic medical industry, fluoroscopy, CT and MCT have put forward more and more stringent requirements on the quality stability, power density and cost of their high-voltage generators. The high-voltage generator is an essential and important part of the X-ray instrument. It is composed of a high-voltage transformer, a rectifier voltage doubler filter circuit, a high-voltage discharge resistor and a sampling circuit. At present, most of the rectification and voltage doubling circuits in X-ray high-voltage generators are based on half-bridge or full-bridge topology, which can only realize the rectification and voltage doubling function, and meet the high kV output (40kV ~ 150kV) by directly conn...
