Abstract

The invention discloses a complementary plasma generation circuit, a control method and a plasma generator. The complementary plasma generation circuit comprises a plurality of pairs of plasma electrodes, a control module and a plurality of boosted circuits, each pair of plasma electrodes comprises a first electrode and a second electrode, and the first electrode and the second electrode are connected with an I / O port of the control module through the corresponding boosted circuits. Complementary PWM waves are output through every two I / O ports of the control module; each pair of plasma electrodes is switched on respectively, so that the problems of arc discharge and sparking under the abnormal condition of the plasma generator are avoided, and the plasma concentration can be improved through an enhancement mode in the environments such as low air humidity, low pollution index and the like in which the arc discharge of the electrodes is not easy to cause; and the duty ratio of the PWMwave can be adjusted to output plasmas with different concentrations.

Description

technical field [0001] The invention relates to the field of plasma generators, in particular to a complementary plasma generating circuit, a control method and a plasma generator. Background technique [0002] At present, the plasma generator is a device that generates a large pressure difference between two electrodes, and then ionizes the air near the electrodes, thereby generating positive and negative ions. [0003] There are two types of power supply for plasma electrode triggering: AC and DC. AC plasma triggers have certain disadvantages in terms of safety due to their high power supply, and it is difficult to promote them well in home appliances; , has certain advantages in application and promotion, but after the low-voltage DC power supply is boosted to high voltage, the two electrodes have a certain probability of arcing and sparking, and there is a certain danger. [0004] The phenomenon of arcing and sparking is a direct current plasma generator. When there is ...
