RE: [TCML] IGBT or MOSFET in series

["miles waldron" <mileswaldron@xxxxxxxxxxx>]

Yes and no. If you can manage a trigger circuit that turns both devices on
and off simultaneously and the devices somehow work then you might get away
with it. If there is too much phase differential then one device will turn
on and "see" a much higer voltage than the device can handle, and it won't
like that. I have had much better luck using those devices in parallel for
higher current handling. I have had bad luck, attempting any series type of
configuration. Whatever the official answer turns out to be, I have tried
both ways and this is my experience.

I have a particular high voltage application for a solid state Tesla coil
design. If I put IGBTs or MOSFETs in series, will their voltage ratings
stack? For example, if I put ten 1,200Vces IGBTs in series, will the string
be able to handle 12,000volts?

 

Take care,

Matthew
