Abstract

The Power Systems Development group at SLAC has developed an improved design for the H-bridge switch plates of the High Voltage Converter Modulators at the Spallation Neutron Source. This integral modulator component has been identified as the source of numerous modulator faults. This paper presents the design and implementation of the alternative switch plate, which is based upon press-pack IGBTs.
