Ozone disinfector 11

Published:2011/6/30 1:28:00 Author:Nicole | Keyword: ozone disinfector | From:SeekIC

The push-pull oscillation circuit is composed of transistors V1, V2, oscillation transformer T2(W1-W3), pulse transformer T1, current limiting resistor R1, charge capacitor C3, two-way trigger diode VD5. The half wave rectifier filter circuit is made of filter inductance coil L, rectifier diode VD1 and filter capacitors C1, C2. The power supply is turned on, 220V AC voltage is filtered by L, it is rectifiered by VD1, it will produce about +280V voltage on the two sides of C1, it feeds to push-pull oscillation circuit. When it is power on, V1 is turned on, due to C3's charge, two-way trigger diode VD5 is cut off.
