Need to do something which requires adding a 2V DC bias to power coming out of the wall (120V, 60Hz), going to a motor. Basically need the 2V DC bias across the motor windings. Motor windings have about a 10 ohm DC resistance. I have a DC power supply that has a max voltage of about 50V. Pic of my circuit posted below, but I think it was frying the power supply because the impedance on the outputs are really low. I'm wondering if there is any way I can do a similar circuit but with some high resistance before the power supply. If not, any idea how I can get the DC bias across the motor windings? Motor represented by the 10 ohm resistor.
