Dear Brian, I'm italian electrical engineer expert in designing power inverters mainly using SCR components which are really preferable under the specific power dissipation and reliability to to sudden gradient of voltage/current to be superimposed to the SCR itself. Over the several technical articles written on the inductive loads topics, nothing related to inductice current coming back from the load to the source. With SCR I have to foresee power diode; with mosfet and IGBT this is automatically achieved due to reverse diode encapsulated. This is over the problem due to first istant peak current and surge voltage at a mosfet commutation switching. What do you think about. Regards, Max
