Many Simple 6V power supply circuit for you

If you need a Simple 6V Power supply Circuit. We have a lot of circuits for you. Some ideas may be good for you working. All circuits use normally components so you can buy any store and cheap. The output DC current 50mA to 3A.

Basic Dual 6V Power Supply circuit

This is a basic unregulated Dual DC 6V Power Supply circuit. The output includes +6VDC, Ground, and -6VDC terminal. In the circuit below we use easily a little electronics components and so cheap.

But it is suitable for the small circuit. Because it can deliver current less than 50mA only. If we use more than this current. It will make the high ripple or high noise.

Working of Simple Dual 6V Power Supply circuit

Simple 6V Dual DC power supply circuit

In the circuit above. First of all, the 110V/220V-ACV flow to the primary transformer T1. It is step down transformer. To change 220VAC to about 6.3VAC at secondary.

Next, both diode – D1, D2 are the half wave rectifier. It converts AC into pulsating DC. The D1 for positive voltage and the D2 for the negative voltage.

Then, both capacitors C1, C2 are used for smooth a fluctuating current into the stable voltage at output about +8.4VDC and -8.4VDC (when low current load.)

In addition. We can reduce the output ripple by using large values for C1 and C2.
We put both resistors R1, R2 to reduce the current so it also reduces ripple.

Choosing the parts
The trasformer-T1 is 220V Primary, CT 6.3V at 100mA Secondary transformer.

We use Capacitors C1, C2 of 100uF 25V. Because the Capacitors volage must have a DC working voltage (WVDC) of at least 2 x 8.4V = 16.8 volts. But we buy 25V because the cost is same as 16V.

Each diode should have 1 PIV, Peak Inverse voltage, a rating that is at least twice the peak voltage from the transformer, 2 x 8.9 = 18V. The 1N4002 has a PIV of 100V.

Many people know that we use half rectifier which it has the high ripple problems. But we require only low current and low voltage. Therefore, it is the profer way for us.
This is basic(Unregulated) Dual DC 6V Power Supply circuit (+6Vdc ground -6Vdc). Which used easily a little electronics components and so cheap.

6V 1A Power Supply Circuit using IC-7806

When we need a 6V 1A DC regulator often use this circuit. The main parts of this circuit is IC-7806. It is normal IC linear DC voltage regulator 6V at 1A current. It is easy project electronic because used the minority part and low cost too.

6V Power supply circuit at 100mA, 200mA, 300mA current

This circuit that you see, It is an one style of an easy simple power supply, for a recorder or a cassette player in the car which used voltage 12V.It is only using the current about 300mA.

6V DC regulator using Zener transistor

When it occured over load current at output.it will not damaged with circuit.(have only current 2Amp) While it can to used the voltage about 6Volt at 800mA max.
The resistance of R1 serves to limit the short circuit current at about 2 amps.And reduce the power consumption of the series regulator transistor Q1.(which acts as the emitter follower circuit with a base voltage from R2, D1).
Here is the diode resistance should be 1 watt or more.

This circuit can be assembled into a small metal box, compact, easily. Using the heater box as cooling plate to transistors Q1 with built-in.
