Performance Advantages
High Efficiency & Low Power ConsumptionAdopting reverse-conducting technology, it features low on-state power loss and achieves approximately 25% higher efficiency compared with conventional thyristors. The snubberless design reduces switching losses, while the gate drive realizes low-inductance connection via coaxial gates and feedthrough PCBs. It completes the mode transition from thyristor to transistor within 1μs, eliminates latch-up risks, and extends the safe operating area (SOA) to the dynamic avalanche region.
Intelligence & High ReliabilityEquipped with a built-in multi-layer protection mechanism, it monitors parameters such as current and temperature in real time. Fault pre-warning can reduce unplanned downtime by 60%. Utilizing industrial-grade components and dual isolation design, it delivers excellent resistance to EMI/RFI, making it suitable for complex industrial electromagnetic environments such as metallurgy and mining.
Flexible AdaptabilityIts compact modular structure facilitates installation, maintenance and capacity expansion through multi-module parallel connection, catering to the power scaling requirements of the ACS1000 system. It is fully compatible with system control and communication protocols, supporting rapid integration and upgrading.

Key Installation & Maintenance Requirements
- Installation must comply with the mechanical and electrical specifications of the ACS1000 system. Ensure the cooling circuit is unobstructed, and the insulation distance between modules meets the 10kV isolation requirement.
- The gate drive must be matched with ABB-specified drive units. Strictly control the gate voltage and drive timing to avoid over-driving, thus reducing energy consumption.
- Regularly monitor the module current, temperature and voltage waveforms via the diagnostic function of the ACS1000 system to predict potential faults and extend service life.
