High-voltage power supply device for diesel engine particulate purifier and output control method thereof

Abstract

A high voltage power supply device for a diesel engine particle cleaner and an output control method of the high voltage power supply device are used for burning particles by the fact that the particles in a diesel engine automobile particle cleaner are sparked, and the high voltage power supply device enables battery voltage to convert to high voltage through inversion. The high voltage power supply device for the diesel engine particle cleaner comprises a storage battery assembly, a direct current voltage stabilizing circuit, a signal operational circuit, a signal modulator circuit, a power amplificatory circuit, a boosting transformer, a high voltage output rectifying circuit, a high voltage signal sampling circuit and a current sampling circuit. The high voltage power supply device for the diesel engine particle cleaner is characterized in that the high voltage power supply device further comprises a single chip microcomputer, wherein feet of input or output (I / O) port of the single chip microcomputer are respectively the input end of the signal modulator circuit and the output end of the current sampling circuit. Feet which are connected with the input end of the signal modulator circuit can output square waves with mutually inverse phase positions. In the time process of the particles accumulating, the single chip microcomputer can discontinuously output the square waves to enable the inversion to happen discontinuously, when the accumulation of the particles achieves the regeneration point, the single chip microcomputer continuously output the square waves to enable the particles to be sparkled and burned, so that the fact that the high voltage power supply device absorbs electric energy from a storage battery is largely reduced.

Description

technical field [0001] The invention relates to a high-voltage power supply device for a diesel engine particulate purifier and an output control method thereof. Specifically, the vehicle-mounted storage battery power is inverted into a high-voltage power supply, which is used for igniting the particulates in the diesel engine particulate purifier to cause the particulates to ignite. Background technique [0002] Before that, I applied for a utility model patent "Electric Breakdown Diesel Engine Exhaust Particulate Purifier", and its application number is "201120209011.2". Use filter ceramics to capture particles in the exhaust gas, and regenerate when the particles in the ceramics reach a certain amount; high-voltage power supply is required for regeneration, and the working principle of regeneration is: the positive and negative terminals of the high-voltage DC power supply are respectively connected to the electrodes in the filter ceramics, An electrostatic field is forme...

Problems solved by technology

[0003] The high-voltage power supply on the market is generally used for electrostatic dust removal, and the power supply provided by it comes from the mains power supply, which is not suitable for working on cars. In addition, there is no suitable one on the market for the requirements of particle ignition in diesel engine car particle purifiers. high voltage power supply, so it is necessary to design a new high voltage power supply
