Self Switching Power Supply Circuit Diagram. By using this circuit we can generate various voltages. And next applied to the regulator circuit system.
First the ac voltage to a power transformer to raise or lower the voltage. So that pin 1 of u1 always outputs a high level that is self locking. The circuit block diagram of the switching power supply is as follows.
Then converted to dc voltage.
Self switching power supply circuit can be used in different electronic types of equipment as the supply voltage. There are many kinds of power supply circuits. Through an arrangement of voltage regulator 7805 and a potentiometer the output voltage is varied from 3 7v to 8 7v. This power supply circuit gives a variable regulated supply and switches off in no load condition.
