The presented new generation of 8.5 kV class Phase Control Thyristors (PCTs) in package with 119 mm pole piece features reduced ON-state voltage VT through optimized wafer thickness, resistivity and cathode design. Additionally, dV/dt and tq ratings were improved as well in the whole range of VT/Qrr values relevant for HVDC and industrial applications. This device completes the new generation PCT platform of ABB, where PCTs with rating currents of 1.5, 3 and 6 kA give designers the necessary degrees of freedom for optimal valve design for HVDC & UHVDC transmission.
