1.2 Rectifier
The rectifier control logic consists of two PCBs.
IF/PS - R Rectifier electronic power supply
• input voltage sensing
• rectifier electronics power supply
CPHC16 - R
Rectifier control and regulation
• rectifier output voltage regulation
• rectifier output current limitation
• soft-start control
• battery charging current limitation
• generation of the thyristor firing pulses
• input voltage monitoring (phase rotation, mains failure)
• control for parallel rectifiers (with a common battery)
• 12-pulse rectifier control
• Second level current limitation for diesel-generators.
• Boost charging according to DIN 41773.
• Thermal compensation.
