I am looking for a circuit that would work to turn an automobile car alternator to run like a motor. I might have already had a circuit to work but stopped short of trying it with a car battery. Would it have worked. I dont have the diagram in front of me but it used a cd4017 ring counter hooked to a 555 timer.I had the 555 timer set up to go from ablout 1Hz to 14 KHz, measured with a frequency counter. The output of cd4017, one-two-three went to a high power mosfet capable of 54 amps each continuous. I had one mosfet for each coil. at the base of the mosfet was a resistor to help the mosfet shut off. I also had the mosfet protected at the load with a rectifier 1n4007. Using high side switching on the mosfet. I even inserted a transistor between the cd4017 and mosfet to make sure the input went from v+ to zero, because I was uncertain if the mosfet was going on all the way and shutting down all the way.. I dont recall the mosfet number as it has been almost a year.
My question is basically this: will it work (assuming the mosfets are big enough) or do you have a better circuit or idea that will make an alternator spin like a motor. Oh and what frequency range and duty cycle?
Something simple or just set me on my way with your ideas.
Thanks. I enjoy your ideas here.
