Description

technical field [0001] The invention relates to a non-isolated rectifier circuit, in particular to a modular high-gain rectifier circuit with adjustable input ports. Background technique [0002] Under the demands of chip high-voltage power supply, ultra-high-voltage positive ion acquisition and acceleration, high-gain rectifier circuits (Voltage Multiplier, VM) and their modeling and analysis methods have been extensively researched and developed since the 1930s. At present, the CW-VM circuit proposed by Cockcroft and Walton and the D-VM circuit proposed by Luscher and Dickson are mainly used at present, and the structures are as shown in the drawings of the description figure 1 , figure 2 As shown, the two circuits are composed of a series of diodes and capacitors, which have the advantages of high efficiency, low cost and simple structure. However, its input power is limited by the overcurrent capability of semiconductor diodes, making it difficult to apply in high-pow...
