OFF-LINE CURRENT-RESONANCE INVERTER Russian patent published in 1997 - IPC

FIELD: conversion engineering; power supplies for ozone electrosynthesis plants. SUBSTANCE: inverter has single-phase transformer 1 whose secondary leads are connected to output leads of inverter; primary windings are center-tapped; primary leads are connected to negative output lead of inverter via first and second thyristors 2 and 3, respectively, and center tap is connected to positive output lead of inverter through choke coil of filter 4; it also has series circuit set up of switching capacitor 4 and switching choke 6 and connected between anodes of thyristors 2, 3, diodes 7, 8 shorting out thyristors 2, 3 in parallel opposition. Connected to output leads of inverter is discharge tube 9 of ozone electrosynthesis plant. Inductances of switching choke 6, choke coil 4, and filter as well as capacity of switching capacitor 5 equal, respectively, , where K₁= 0.5-0.7; K₂=7-10; K₃=0.4-0.5 are constants; E is inverter supply voltage; ω is control frequency; P is inverter output power. EFFECT: enlarged functional capabilities. 1 dwg
