The ozonator power supply comprises a lamination busbar and a rectifying unit, a current-limiting soft start unit, a filter unit and a full bridge inverter unit which are in electric connection with one another, wherein the filer unit is arranged on a power supply base plate which is provided with a cooling fin; the cooling fin is provided with the rectifying unit, the current-limiting soft start unit and the full bridge inverter unit; the filter unit and the upper portion of the full bridge inverter unit are connected with the lamination busbar, and the lamination busbar comprises a negative pole plate, an insulating layer and a positive pole plate which are arranged in sequence; the rectifying unit, the filter unit, the full bridge inverter unit and the current-limiting soft start unit are in electric connection with the lamination busbar. According to the ozonator power supply, special lamination busbar parameters are adopted, influence of switching stress on an inverter switch tube is reduced, the reliability of the power supply is improved, the design of a snubber circuit is simplified, and the structure of the ozonator power supply is compact.

Description

technical field [0001] The invention relates to the technical field of special power supplies, in particular to an ozone generator power supply. Background technique [0002] As a strong oxidant, ozone has significant effects in disinfection, disinfection, decolorization, and organic matter treatment. Because ozone is easy to decompose, ozone usually needs to be prepared on site. The main method for industrial preparation of ozone is the dielectric barrier discharge method. In the early days, DBD ozone generators used power frequency step-up power supply to discharge, which produced low ozone concentration, high power consumption, and large power supply volume. With the continuous expansion of ozone application fields, higher requirements were put forward for the technical indicators of ozone generators. , the way to improve these indicators is to increase the frequency of power supply. [0003] Ozone generator load characteristics are different from common inverter loads, ...
