Role in the system and operating principle
Operating principle
AC voltage is adapted and isolated by the transformer, then rectified by the thyristor bridge. Firing angle and filtering control the DC bus and battery charging voltage.
Maintenance and lifecycle
Transformers, power semiconductors, capacitors, fans, connections and calibration values are checked periodically. A spare-parts plan is established for critical components.
APPLICATIONS
Engineering for the duty profile.
- Power plants and substations
- Oil, gas and petrochemicals
- Steel and mining
- Rail systems
- Heavy process facilities

TECHNICAL QUESTIONS
Frequently asked questions
Why choose a thyristor system?
It is a strong option where high power, galvanic isolation, demanding site conditions and long service life are priorities.
How does it differ from a modular rectifier?
The power stage is generally centralised and project-specific within a cabinet. A modular system builds capacity using hot-swap modules.
