13.8V Power Supply Circuit Diagram
Here is a 13.8V power supply circuit for heavy-duty power supply to the load 20A or 30A continuous. Power supply is mostly intended for HAM radio transmitter with a low ripple, HF-immunity, and short-circuit protection features.
At maximum load, the 13.8V power supply has a voltage level of voltage drop of 0.35V DC and the output can be set between 12.3V and + /-15V. The ability of the load on the power supply can also be set to load 20A (4x 2N3055) and
