Highly compact, high-speed, electrically driven radial turbo compressor with expander and gas bearing for the compression of air for fuel cell systems.
Highly compact, high-speed, electrically driven radial turbo compressor with expander and gas bearing for the compression of air for fuel cell systems.
▪ High-speed gas bearings for oil-free operation
▪ Expander for energy recovery of wet air
▪ No air-cooling requirement for gas bearings enabling significant system efficiency advantage
▪ Aerodynamic and electromagnetic optimization for highest total efficiency
▪ Integrated temperature measurement for overload protection
High-voltage boost inverter for driving ultra-high-speed turbo compressors in medium and heavy-duty fuel cell systems in mobile, stationary or marine applications. The integrated boost front-end ensures that the maximum inverter output voltage (800 Vpk) is available across the full the HV voltage range (250 to 920 V DC), enabling motor control at maximum speed even where the back EMF exceeds the input voltage. Additionally, the consistently high inverter output voltage results in a reduction of the phase current and the cable cross-section of the motor cables to just 6 mm2 at 25 kW compressor power, simplifying integration on the system level.
▪ Designed for the Celeroton TurboCell air compressor CTE-4000 and optimized for fuel cell applications.
▪ Power electronics with maximum power density at highest inverter efficiency
▪ Operation of turbo compressor with maximum speed from wide HV voltage range (250 - 920 V DC)
▪ Continuous compressor power of > 25 kW available from HV voltage > 520 V DC without derating
▪ Sensorless PMSM speed control up to 140,000 rpm
▪ Protection class IP67 and IP6K9K
