Adjustable Stabilized Power Supply 0 15V 5A

Adjustable Stabilized Power Supply 0-15V / 5A

This
adapted ability accumulation can be adapted amid a few volts and 15V
with P1 and with P2 acclimatize the high absolute ( 15.0V ). R6 amount
is 0.7V / Imax area Imax is the best current. At Imax = 5A, R6 is
0.14Ω

T1 and T2 charge accept
heatsinks because ability losses are abundant at a low achievement
voltage and a Imax according accepted but you can affix the lamp L to
abate this losses.

I’ve body
this adjustable ability accumulation and works great! I achievement
you’ll adore it too and accept fun body this abundant counterbalanced
ability supply.

5 to 15V Regulated Power Supply Rise

Regulated Power Supply

This project is a normal DC regulated power supply that is a variable DC voltage range from 5V to 15V. It can supply current up to  400mA to power the various circuits for your electronic projects. The voltage output is varied by using the potentiometer V.R1. In this circuit, the input line power supply is designed for 240V.A.C. If 110VAC input is used, alter the ratings of the varistor to 150VAC & the transformer ratio to 110V/12V. 

Fuse F1 is used as a protection in case theres any short circuit in the circuit. Varistor V1 is connected in parallel to the input of the line voltage to clamp the surge voltage from the line to a reasonable level that helps to protect the transformer & other circuitry. One time the voltage level surge to a high level beyond the ability of the varistor to absorb it, fuse F1 or varistor V1 or both will burn. If this circuit failed after a period of operation, check that the fuse & the varistor are still in nice condition or else replace them.

Diodes D1, D2, D3 and D4 are used to rectify the 12V.A.C voltage to DC voltage. Electrolytic capacitor E1 is used as a smoothing capacitor to reduce the ripple of the DC voltage. The DC voltage is fed in to the input of 7805 regulator where the output DC voltage is obtained. Changing the worth of VR1 will alter the output of the DC voltage. Capacitor C1 is used to filter out high frequency part from the power supply.
