BRUSA Elektronik AG develops a new range of inverters for AC electric drives up to 900VDC / 200kW. The extremely flat units (below 100mm) are intended for hybrid / electric cars, buses and trucks. Prices will be comparable to conventional designs, while volume and weight are cut in half. Universal design and flexible software - employing vector control - supports all types of AC motors (induction, PM synchronous, hybrid synchronous) from high torque to high speed drives. The model DMC524 (400V/80kW) is available already, additional models will follow shortly.
Features:
- Continuous power range 15 - 160 kW
- 2 nominal voltage ranges: 360V and 720V +/-33%
- compact and lightweight: up to 10kW/kg
- Proprietary SoftSwing topology:
- high efficiency and low EMI
- fast and smooth regulation due to high PWM frequency
- no degradation of motor isolation
- high speed applications
- Control algorithms for AC induction, hybrid synchronous and PM synchronous motors
- Torque, speed and power control
- CAN BUS and analog control interface
- Control supply from high voltage or 12V/24V auxiliary board supply
- Input and output common mode filters included
- Integrated cable box for easy installation
Applications:
- Automotive drives for hybrid and fuel cell vehicles
- Hybrid bus traction or generator inverter
- Drives for Streetcars, Trolleybuses, Metros etc.
- Turbine applications (Turbo-generator, Compressor)
- High speed machining tools
