| Fig 1 – Stabilized Power Supply 13.8V High Current 10 Amps |
This is an excellent and simple stabilized power supply of 13.8V and high current, 10 Amps. This power supply has great stability, and you can use it with a large number of projects, such as:
- Power supply for Radio Amateurs: Which need a high current and excellent stabilization to work
- Batteries chargers: Since, 13.8V is a good voltage to charge most batteries, automotive sound power supply, etc.
Finally, it can be used for countless types of projects, not to mention that its assembly is easy to build, using discrete components that are easy to acquire.

The Transformer
The power transformer must have a supply capacity of at least 10 Amperes, this taking into account that you want to use this circuit for 10A.
You may be using a power transformer with a smaller capacity that will not harm the circuit, just making it clear, that if a power transformer with a lower current is placed, for example, 5A, at the output you will have a maximum of 5A.
I said at most because, we know that there are losses due to dissipation, conversion, etc., but it’ll work, the voltage of the transformer must be at least 12Vac, and a maximum of 18Vac, for a more efficient operation.
