This is a simple zener diode regulator circuit ,Simple Fixed regulator, multiple output voltage are: 12V, 15V, 30V
Today we come to see the high voltage Generator circuit ideas, that it can converter the AC line 110V or 120V to DC900-volts. In circuit use 8 x voltage input. When see this circuit also we use technique Diode and Capacitors.
This is four circuits of LED voltage indicator are simple and easy to builds for check voltage battery and others, use as zener,transistor,LM339 and more
