12V to 24V DC Converter Circuit


12v to 24v DC converter circuit 300x185 12V to 24V DC Converter Circuit

This is a very simple 12V to 24V DC converter circuit, delivers up to 24V from a 12V supply. It is able to be utilized to run radios, small power of lights, relays, horns and also other 24V equipment from a 12V vehicle having a maximum draw of about 800mA. It could be utilized to charge one 12V battery from another, or step up the voltage just enough to supply necessary overhead for a 12V linear regulator. Working with one operational amplifier as being a squarewave oscillator to ring an inductor and another op-amp in a feedback loop, it is not going to drift around under varying loads, delivering a stable 24V supply for a lot of applications. Using a wide adjustment in output, this circuit has a lot of uses.

Components List
R1, R2, R3, R4, R8, R7 = 100K 1/4W
R5 = 470 Ohm 1/2W
R6 = 10K Linear Potensiometer
C1 = 0.01uF
C2 = 0.1uF
C3 = 470uF/63V
D1 = 1N4004
D2 = BY229-400
Q1 = BC337
U1 = LM358
L1 = See Notes
MISC = Board, Wire, Socket For U1, Case, Knob For R6, Heatsink for Q1

12V to 24V DC Converter Circuit Notes:

  • D2 can be any fast recovery diode rated at higher than 100V at 5A. It’s really vital that the diode be fast recovery and not a common rectifier.
  • Mount the transistor Q1on a heatsink to prevent overheating.
  • R6 sets the output voltage. This could be calculated by Vout = 12 x (R8/(R8+R7)) x (R6B/R6A).
  • L1 is created by winding 60 turns of 0.63MM magnet wire on a toroidial core measuring 15MM (OD) by 8MM (ID) by 6MM (H).
