| Abstract |
We describe an accurate current source for fast field cycling Nuclear
Magnetic Resonance (NMR), employing paralleled IGBTs operating in the active
zone.
We present and discuss aspects of the implementation of paralleled IGBTs working
in the active zone, the design of the controllers needed to obtain response times in
the ms range, together with simulation and experimental results. |
