High-voltage MPM modular modulation power supply for EIK klystron

Abstract

The invention relates to a high-voltage MPM modular modulation power supply for an EIK klystron and can solve a technical problem that a traditional MPM power supply module cannot meet the power supply requirement of the EIK klystron. The power supply is characterized in that after the commercial power passes through an EMC filter and is rectified and filtered through a power supply module into adirect-current 300V power supply, positive and negative 15V low-voltage power supply is generated in the power supply module by utilizing a high-frequency DC / DC module, the 300V direct current power supply of the power supply module is supplied to an auxiliary power supply inversion module and a main high-voltage power supply inversion board at a rear stage, the power is subjected to high-frequency inversion of two types of inversion units and then is sent to respective rear-stage high-frequency transformers and rectifier circuits, and the main high-voltage power supply rectifier supplies power to the final EIK klystron together with a floating modulation power supply, a filament power supply and a bias power supply. The power supply is advantaged in that the rectified direct-current powersupply of a power frequency alternating-current mains supply is outputted to a floating power supply module through the high-frequency transformer after being subjected to high-frequency inversion, and high-power energy transmission and high-voltage isolation are realized by using a small size.

Description

technical field [0001] The invention relates to the technical field of high-voltage power supplies for EIK klystrons, in particular to a high-voltage MPM modular modulation power supply for EIK klystrons. Background technique [0002] The distributed action klystron (referred to as EIK klystron) has the characteristics of large peak power, small size, and high microwave frequency. Commercial products in multiple frequency bands have appeared in the millimeter wave and above frequency bands. However, its cathode operating voltage is high, and the power supply is required to be small in size. [0003] The traditional MPM (Microwave Power Module) high-voltage power supply is generally designed for broadband traveling wave tubes, and its cathode operating voltage is less than 10kV. The filament, modulation, etc. are potted and designed together with the cathode high voltage, and the volume is comparable to that of traveling wave tubes. . However, because the cathode working vo...
