The nine thyristors deliver continuous on-state current from 12 to 79A rms, while the diodes, both standard and fast recovery types, offer forward current from 8 to 65 A. All devices provide up to 1kV ...

High current, isolated base dual thyristor and diode modules are available with eight different configurations of Diode, Thyristor and thyristor/diode combinations. IXYS UK has an extensive range ...

All modules are offered in the topologies thyristor/thyristor and thyristor/diode with a blocking voltage of 1600 V or 2200 V and in current ratings from 420 A to 630 A. Additional module types in 70 ...

Fast Turn Off Thyristor and Fast Recovery Diode Module are available between 55A and 400A at 600V to 2500V and the Fast Recovery Diode Module have power ratings of 75A to 400A at 600V to 1800V.

[Part 1 begins with an overview of the operation of thyristor-fed DC motor drives.] Converter output impedance: overlap So far we have tacitly assumed that the output voltage from the converter was ...
