Currently working on a project to make an electrical "gear" in a three phase PMSM. To do this I am going to reconfigure the stator windings from series to parallel. Each phase has four windings, but I only want to be able to parallel connect two and two. I have made the decision to use back-to-back MOSFETs as this seemed to be the most efficient and cheapest option (triac is an option as well, but as I understood, the control is more difficult). First question will be, what is the optimal switching circuit?
Second, I need to control the MOSFETs. The motor runs on a 44 V battery with an inverter. Would it be possible to use this power supply for MOSFET control? If so, how? Would appreciate a circuit diagram of potential solutions
The motor is to be used in drones with three phase RMS currents reaching levels of 100A in the parallel connection.
