Figure 2 - Basic 10A Power Supply - Regulator Section. As you can see, the regulator is made adjustable over a small range, and will typically give from 11V to 13.8V at full load. With the no-load voltage set to 13.8V (nominal 12V battery voltage), the output will fall to 13.5V at about 1.5A, and 12.8V at around 13A.

13.8v Power Supply Circuit Diagram for Mobile Rigs
The 13.8v power supply Circuit Diagrams shown below are based on a type 723 voltage regulator because it is reliable, widely available and cheaper than many of the latest high-power (>1.5 A) three-terminal voltage regulators. The 723 IC comes in two packages; a 14-pin DIL case or a 10-lead metal can. The pin connections and pin numbers are ...
Testing the Power Supply. Phase 1: These tests have to be carried out at a low DC supply voltage in order to avoid component destruction in case of possible errors. The 13.8 V output is loaded with a 12 V / 50 W car headlight bulb and a 15 V / 1 A lab power supply is connected to GND and Uaux.
This power supply delivers a highly regulated 13.8V, adjustable over a moderate range, at a continuous current of up to 20A. It is current-limited to approximately 25A, and short circuit protected for as long as the heat sink can keep the transistors cool enough. It is probably the simplest design that can accomplish this.
How to build 10 Amp 13.8 Volt Power Supply (circuit diagram)
The circuit uses 3 pass transistors which must be heat sinked. Resistor R9 allows the fine tuning of the voltage to exactly 13.8 volts and the resistor network formed by resistors R4 through R7 controls the current limiting. The LM723 limits the current when the voltage drop across R5 approaches .7 volts. To reduce costs, most commercial units ...
