Published:2011/6/15 7:34:00 Author:Borg | Keyword: power supply generator, NAND
In the electric instrument, there often needs a team of low-power passive power supplies, which can be assembled with 3 NAND in the figured way, then the power supply polarity can be changed quickly. The the circuit, A1 and A2 form a self-motivated multi-resonance oscillator whose frequency is about 4KHz, A3 is the buffer which is also the rectifier. When the oscillating circuit A3 is outputting a high LEV, VDI is conducting, C2 is charged, A is positive and B is passive, VD2 is blocked. When A3 is outputting a low LEV, as the voltage on the two poles of C2 can't mutate quickly, so the 8 points are in a passive voltage. (View)
