Today I seeks mini power supply regulator give friends try out again. Be fixed voltage regulator 9V size. It uses transistor be pillar equipment perform boost up current tallly go up about 300mA. And by have Zener Diode perform steady voltage at 9Vdc. The detail is other a friend sees in the circuit please yes. [...]
This be Mini high voltage generator at my friend wants. Because of use the transistor 2 pcs only just,build small-sized easy good. By this circuit gives pulse Generator 220V from 9V batteries and Give pulse voltage tall arrive at 170V from the 1 dry piece cell(Batt 1.5V) we should do circuit this experiment with neon [...]
Today I searches the circuit in old book. Meet power supply circuit. very plentiful may advantage with friends. Then bring see this circuit basically the base of DC voltage Regulator follow the circuit gives voltage , get +13V and -13V by it uses Zener Diode . Perform maintain one’s position voltage. Be stable and use [...]
