Thr power supply is a switching one and i cant do that... i am using a 12v 20amp psu that is connected to a buck boost converter (ltc3780 to be exact). So kermit2' s schematic would work for sure?If the bench psu is yours, you could use the transformer outputs to give you 30V AC, you would need to measure its output and put a couple of yellow 4mm sockets on it. If you want variable ac your better using a variac transformer , otherwise its an inverter.
I have a switch mode power supply attached to a buck/boost converter which in return gives me a range between 0-30v 10a. Im basically looking for a circuit that enables me to change Dc to Ac without a voltage change....You said your psu is a switchmode type, it will alter the pwm to give a variable voltage, unless you're wanting to make an inverter which to me is a waste, use a small transformer to drop the mains 120V or 230V to 30V to test the motors, or if you want a variable AC supply use a variac.
