I have a single voltage source +54 volts. My project requires a symmetrical power supply 50-0-50. Is there a way I can manipulate my single power supply to give me split supply? |

A possible solution is to use two equal resistors in series. And now, build your circuit taking the ground as the middle point, the point between the resistors. Take resistors about 100 times less than the value of the reactance of your circuit to minimize the influence of your circuit over the voltage divider, but note that a small resistor implies more thermal lost. You may have to use a voltage divider with bigger resistance values, but with an OpAmp to minimize the possible unbalancing of your circuit OR use a specialized DC drop down circuit and again, use that point as the new ground |
