Zusammenfassung:The paper presents adjustable speed generation system with a newly designed and built axial flux shaftless and bearingless permanent magnet generator, and power-electronic converter acting as universal AC power source. Speed of the prime mover is adjusted to meet load demand by real time load measurement and calculation. Thus the power electronics converter decouples the generator and load and then rotation of the generator is not related to electrical power system stability. Then such a system has another degree of freedom related to speed. The system is controlled by a Share DSP processor and provides high quality of the output power. Results of tests of 40 kVA power system driven by a Diesel engine are related to steady state operation and to transients. The system can operate with 100% of asymmetrical phase load with any changes o f output voltage. Oscillogram of step load operation confirms ability to accept 45% sudden change of load without any voltage distortion.
