- 描述
The Power Unit is intended for use as a part of a three-phase three-level voltage inverter with T-NPC topology, which converts direct voltage into regulated alternating voltage as a part of a high-voltage frequency converter.
It is possible to increase the rated power of the unit.
-
High design reliability and serviceability (module replacement time is 30 min)
-
Power scalability in parallel connection
-
High power density (11 kW/l) due to the use of the Press-Pack IGBT transistors and the Press-Pack FRD diodes in disc design with the double-sided liquid cooling of own production
-
Transistors and Diodes as a part of the unit provide the maximum output power of one phase of the inverter of up to 5 MW
-
Optimized cooling circuit topology
-
Galvanic isolation of gate circuits
-
Isolated driver power supply via a current loop
-
Dielectric strength of 10.25 kV (RMS)
All power stacks except semiconductor switches can be equipped with snubber circuits, resistive dividers, drivers, current, voltage and temperature sensors. Proton-Electrotex can design and assemble power stacks customized per individual inquiry.
