Testing high power, high brightness light-emitting diode (HBLED) modules is increasingly challenging. One crucial characterization function is the ability to detect which modules are affected by the ...

IXYS Corporation announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., just introduced an extensive range of new high current isolated base dual thyristor and diode modules. IXYS Corp.

TDK Corporation presents the new EPCOS TSM-LC-S thyristor module for dynamic power factor correction (PFC). It is designed for voltages of 200 V AC to 440 V AC (50/60 Hz) and is suitable for ...

The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all four quadrants are tested, which is done with S3, while in case of ...
