Description
This is electronic circuit of Electronic Circuit: Amplifier Power Supply 24V 2A Based on TIP122 for you. According Eleccircuits blog mentioned that when the load-use many currents. The output voltage still voltage of 24V, and low ripple. So low noise on the speaker of your amplifier. Of cause, we can use this circuit for any circuit and can change voltage output as you need. And this circuit has a few parts and easy to buy in most of the local markets.
The AC-voltage to the power cord, transformer T1 changes 230VAC(PRI) to about 24VAC(Sec). Then, the rectifier bridge, D1 through D4, rectifies the AC into pulsating DC.
Next, A big electrolytic capacitor-C1 filter the pulsating DC to smooth DC voltage about of 36V. But this is not complete. Because of It is not DC regulated voltage of 24V at 2A.
After that, the DC voltage flow through the R1 to Zener Diodes (ZD1, ZD2) to keeps the voltage constant at 25V. This voltage across the base of Darlington transistor Q1 to bias it working full current more than of 2A.
The capacitors C2, C3, C4 acts as a storage capacitor to reduce the noise of output. This makes constant voltage across the output of 24V. The LED1 show power on of circuit, which the R3 is its limiting current resistor.
