FREQUENCY CHANGER FOR OZONIZER FEEDING Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: ozonizer feeding frequency changer is characterized in that rectifier output is connected to inverter input through two filter chokes and inverter input leads are shorted out by first series circuit set up of second diode, second capacitor, third diode, third capacitor, and fourth diode; anode of second diode is connected to cathode group of inverter and its cathode, to first lead of second capacitor; anode of third diode is connected to second lead of second capacitor and its cathode, to first lead of third capacitor; anode of fourth diode is connected to second lead of third capacitor and its cathode, to anode group of inverter; common point of connection of second diode and second capacitor is connected to positive output lead of rectifier through second series circuit set up of fourth choke and second resistor; common point of connection of third diode and third capacitor is connected to positive output lead of rectifier through fourth series circuit built up of fifth choke and third resistor; common point of connection of third capacitor and fourth diode is connected to negative output lead of rectifier through fifth series circuit set up of sixth choke and fourth resistor. EFFECT: improved circuit arrangement. 1 dwg
