I have made a power supply where I am taking in 24VAC from a transformer, and converting it to 10VDC, through a bridge rectifier and a switching regulator circuit. The 10VDC is being used to generate a 0-10V signal with a pot to control an actuator motor position. The actuator motor uses the same 24VAC for it's power that is used for the power supply. There are only 3 terminals on the actuator - 10VDC signal, 24VAC power, and common ground. My question is, will I have any problems if I connect the zero voltage output of the DC power supply to the neutral of the 24VAC transformer? Also, should I ground the neutral output of the transformer as I was planning? This whole circuit works fine when applying 24VDC power to the input, but I don't want to try it with AC without finding an answer to this question.
