OZONE GENERATOR AND POWER SUPPLY THEREFOR Russian patent published in 2016 - IPC C01B13/11 H02M7/00 

FIELD: instrument making.

SUBSTANCE: invention relates to small-size ozonisers modular type and can be used for treatment of warehouses and storages from pests, bacteria and microbes, as well as in household purposes for purifying and disinfecting domestic premises. Ozoniser has a power supply and ozone generator, which includes dielectric frame, first and second electrodes with dielectric barrier between them, connected to power supply. Dielectric frame of ozone generator is made from plate glass-cloth laminate double-sided printed circuit board of copper foil which on both sides of plate glass-cloth laminate has two first electrode connected to first output of power supply. Dielectric barrier is made in form of two plates of mica 0.1-0.3 mm thick, located on both sides of plates from copper foil of first electrodes. Second electrode is single copper wire with diameter 0.1-0.3 mm, in one layer of wound on top of plates of mica in form of direct and reverse spiral pitch 2.5-10 mm, and is connected by both ends to second output of power supply. Power supply of ozoniser has a dc voltage source, a high frequency voltage generator and a transformer connected to control unit, which is configured to generate pulses frequency 10-40 kHz to set period of 6-11 ms, pulse generation time in one period of 1 ms and pause in period of 5-10 ms. High-frequency voltage generator comprises two electronic switches, made in form of two field-effect transistors. Transformer contains an additional negative feedback winding connected to a dc voltage source via control unit. Between source of dc voltage and high frequency voltage generator is installed measuring resistor connected with control unit.

EFFECT: simplified design, manufacturability, higher reliability and stability of operation, reduced dimensions, reduced cost and power consumption.
