Abstract

The invention discloses a molecular decomposition alternating-current driver comprising a rectifier voltage-regulating circuit, an alternating-current decomposition core circuit and a decomposition reactor. The alternating-current decomposition core circuit consists of an external power supply Ui, a compound level generation circuit, and a variable boost resonance circuit; the compound level generation circuit generates different levels and the variable boost resonance circuit realizes outputs of different drive energy levels. According to the molecular decomposition alternating-current driver, outputs at different energy levels is realized for different decomposition needs. Compared with the traditional fixed resonant output device, the driver enables the energy output form to be optimized, the energy utilization efficiency to be improved, the resonant transformer size to be reduced, the service life of the molecular decomposition driver to be prolonged. The control plan is simple and is easy to implement; and the reliability is high and the cost is low.

Description

technical field [0001] The invention relates to the field of environmental protection treatment, in particular to an AC drive for molecular cracking. Background technique [0002] With the development of the environmental protection industry, molecular cracking has been widely studied and applied, but in industrial occasions that require high frequency and high voltage, molecular cracking still uses square wave output, and its output level is only +U and -U. Level, and the circuit topology is only half-bridge and full-bridge. Although the square wave output control scheme is simple and easy to implement, the switching loss is high, the conversion efficiency is low, the total harmonic distortion is high, and the voltage stress on the power triode switch tube is very large, which makes the power triode switch tube easy to damage. Although the equipment cost of the half-bridge is not as high as that of the full-bridge, the output voltage of the half-bridge topology is only hal...
