Negative oxygen ion generator 3

Published:2011/6/28 1:23:00 Author:Nicole | Keyword: oxygen ion, generator | From:SeekIC

This negative oxygen ion generator circuit is composed of TRIAC VT, diodes VD1-VD3, resistors R1-R4, capacitors C1-C3, boost transformer T and electrode pad, it is shown in the figure 9-115. The bleeder circuit is made of R1 and C1, the phase shift trigger circuit consists of VD1, C2, R3. At the negative half-cycle of AC, rectifier diode VD2 turns on, after rectifying, the pulse DC voltage charges to C3 by R2, when the both sides of C3's voltage reaches peak value, VT is triggered and turned on. When the AC passage zero, due to C2's phase shift action, C2's voltage also can make VT turned on.
