PARARESONANCE METHOD OF VOLTAGE STABILIZATION OF HIGH-FREQUENCY OZONIZER AND DEVICE FOR METHOD EMBODIMENT

摘要

FIELD: intensification of oxidation processes, decontamination of environments, agriculture and other branches of national economy. SUBSTANCE: used for pararesonance method of voltage and current stabilization of ozonizer, generating ozone due to high-frequency barrier discharge, is power supply source in the form of alternating voltage generator with internal inductive impedance, ozonizer voltage drop U_oz = I_oz/2πf•C_oz, where f is ozonizer current frequency; I_oz is ozonizer current intensity; C_oz is ozonizer nonlinear capacity. Ozonizer current frequency f is proportional to effective voltage U_L on inductive impedance and its nonlinear capacity C_oz rises with increase of U_oz. Power supply source is in the form of semiconductive semibridge consisting of two transistors and two capacities. One of bridge diagonally opposite pairs are connected to direct voltage, and the other one is connected to primary winding of high-voltage transformer having coupling coefficient between the primary and secondary windings equalling 0.7-0.9, and two control windings from which supplied through resistors to base circuits of said transistors are voltages proportional to transformer primary voltage to provide for alternating switching of bridge opposite arms. EFFECT: higher stabilization of operating conditions with voltage fluctuations in supply mains. 2 cl, 5 dwg
