Hey all. I'm currently developing a controller for an eddy current brake. Basically what I need to do is apply a DC voltage to it, up to 192V, and it will proportionately apply a torque. As far as I'm aware, I can accomplish this by either using a controlled SCR and then rectify, or use a PWM and some power stage with a rectified current. Anyone knows of the advantages and drawbacks of each? Or have you worked with eddy current brakes before (maybe one or both of these approaches are not really viable)?
Any info you can shed on this is really appreciated!
