Abstract

The invention discloses a high-voltage pulse switching power supply, which comprises a rectifier module and a master control module, and is characterized by further comprising an MOS (Metal Oxide Semiconductor) tube driving module and a chopping and boosting module, the input end of the rectifier module is electrically connected with commercial power, and the output end is electrically connected with the input end of the master control module; the output end of the main control module is electrically connected with the input end of the MOS tube driving module, and the output end of the MOS tube driving module is electrically connected with the input end of the chopping and boosting module; the chopping and boosting module comprises a reaction transformer for obtaining high-voltage direct-current voltage and supplying power to the outside; the master control module mainly comprises an STM32 single-chip microcomputer and an auxiliary peripheral circuit thereof. And the MOS tube driving module comprises an IR2117 chip. Therefore, the high-voltage pulse switching power supply is small in size and high in working efficiency.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a high-voltage pulse switching power supply. Background technique [0002] Plasma air purifier is a kind of equipment that uses high-voltage power supply to generate plasma to purify the air. It needs several thousand volts of high-voltage DC voltage in its work. At present, the mainstream switching power supply in the market is mainly DC switching power supply, and most of them are low-voltage voltage, and the volume cannot be small enough, which limits its application field. In order to make up for this market vacancy, it is necessary to study a high-voltage pulse switching power supply with higher efficiency and voltage, smaller volume, lower energy consumption, and intelligent adjustment of frequency and duty cycle to indirectly change the average voltage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ...
