High voltage power supply for mobile environment and production method

Abstract

The invention relates to the technical field of a high voltage power supply. The invention provides a high voltage power supply for a mobile environment and a production method, in order to solve the problems of the prior art. The high voltage power supply is supplied according to the power supply requirement for high-parameter pulse power supply under the mobile environment. The low-voltage and low-power (typically 24V-32V/below 1 kW) power supply condition is utilized to realize instant high-voltage and high power (typically 100kW/10kW) output parameter. An electrode of a capacitor set, a power supply (external) and direct current input ends of a plurality of inverters are in parallel connection with each other; an alternating current output end of each inverter is respectively connected with a primary coil of a transformer; a secondary coil of each transformer is connected with an alternating current input end of a rectifier; the direct current output ends of n rectifiers are serially (cascading) connected with each other through a wire and are used for outputting high voltage; when the high-voltage power supply runs, the outputted electric energy is mainly supplied by the capacitor set; the capacitor set has higher capacity and can meet the repeated recharging requirements of the loads.

Description

technical field [0001] The invention relates to the technical field of high-voltage power supplies, in particular to a high-voltage power supply used in a mobile environment and a production method. Background technique [0002] The development of miniaturized and repeated-frequency pulse power technology has enabled some compact repetitive-frequency pulse power devices to be portable and can be used in outdoor environments. An important feature of the outdoor application environment is that the supporting power supply capacity is relatively limited. For example, the power supply parameters of some commonly used battery packs are within 32 V / 1 kW. However, the repetitive frequency pulse power device has high requirements on the power supply during operation. Some high-parameter devices have a charging voltage greater than 100 kV and a charging power greater than 10 kW. Therefore, the battery pack power supply parameters are far from meeting such demands.

AI Technical Summary

Problems solved by technology

A transformer is used to boost the voltage from 32 V to 100 kV. Because the transformation ratio of the transformer is too high, its parasitic capacitance parameters are significant, and it is generally difficult to meet the performance requirements. With the multi-voltage rectification method, the power density of the power supply cannot generally be made very high, which affects the power supply. Device compactness and miniaturization

In addition, none of the existing high-voltage power supplies involves the use of input power less than output power, and cannot be used under the above-mentioned low input power conditions
