High current voltage regulator circuit
High current voltage regulator circuit
The electronic circuit  for DC voltage 5-12 Volts or -12Volts regulator isolated from double LM317 IC-12V. Power supply for 4V to 6V, current 0.3A. 
Details of this circuits.
 
A power supply of  low voltage 5V. function of regulation by LM317  When +5VDC want but the total of the input voltage is 5.1V only slightly.
Heavy possible that we see in this fuel system low-voltage devices to regulation by the LM317.
The circuitry by low job control have low voltage drop in the circuit a lot. The important point for this new type of circuit use IC LM317 very popular. Then make sure that no heavy equipment safely. If the circle of thinking, the use of LEDs ensures that a voltage regulated then mainly in the direction of the work of the racetrack. Normally, this route, the input voltage of 5.1V to 12V. Q1 TIP42 also improve current tallly carry up to 2A. Completion of this course is really useful, a friend of the joy of the Lord Mail.
Applications
1.Flyback controller
2. Multiple-output regulator
3. Simply promoting regulator
4. Forward Converter

13.8 Vdc High current power supply circuit 2

13.8 Vdc High current power supply circuit 2

The circuit is high current power supply  which is 13.8V at 20A. That, we can get base equipment which seeks to buy easy, IC LM741 ,founction one’s position voltage be stable or regulated at 13.8V.

which can fine decorate a little again. Besides still have the power transistors 2N3055 X4 numbers bring to build parallel perform enlarge current tall arrive at 20Amp Other detail , Please understand in the circuit.
