Überblick
A device for controlling three-phase thyristor bridges and phase-controlled rectifiers.
Using a 'pulse refresher', it is possible to control parallel thyristor bridges. The firing pulse repeater selects and forwards firing pulses and has control and monitoring functionality. The PR operates based on programmable logic technology (CPLD); this guarantees the highest degree of operational safety.
