3 phase switch relactance motor

[Kasim]

Hi

Im doing a project to control a 3 phase switch relactance motor using power electronics. I have choosen 3 mosfets, 2 auto couplers and 2 resistors.

1. Would there be any other devices I need ( to solder to pcb board).
2. What would the circuit digaram look like so I can solder this and test it.

Thanks

Hello Kasim - welcome.

Hove you done any research on three phase switched reluctance motors? Typically you will not control a three phase with 3 switch configuration (MOSFETs) - probably needs at least 4 but 6 Sw and 6 Diode set up is most common.

Thanks for the reply.

It is group work and I have been told to do the circuit diagram. I think I've mis-writen the question previously asked.

Basically we will be using a software simulation to design the driving signals to the 3 phase srm. I am guessing the mosfets are just going to act as switches so like in the link you have provided will only switch phase a,b or c at any given time when a current is applied.

Does this make sense now ? If so how would the circuit diagram look.

Thanks again

Yes the MOSFETs are switches - but you did not look at the AP note I linked to.

Ok thanks il look at that
