This article proposes a novel dual-three-phase high-power high-speed permanent magnet assisted synchronous reluctance starter generator (PMaSynR SG) for aviation application, which has the characteristics of high efficiency, power density, reliability, and excellent antishort-circuit ability. The proposed PMaSynR SG can obtain higher efficiency density by embedding in rotor topology compared with generator, better ability starter-generator. Moreover, design winding is adopted, not only...
Permanent-magnet-assisted reluctance (PMAREL) machine possesses the potential as aircraft starter/generator (S/G) for its high power density, efficiency, and tolerance to short-circuit faults. For S/G systems, voltage build-up is a prerequisite generation. However, of PMAREL system may fail if initial dc-link low control fast-response. In this article, mechanism failure clarified. The conduction feature devices in electronic converter when clamped at 0 V are explored. Conditions clamping all...
Flying start of a permanent magnet generator (PMG) connected rectifier is common requirement in practical applications. This paper proposes novel flying method using the short-circuit-current vector (SCCV) increments. The proposed eliminates limitations conventional zero-voltage pulse methods that response currents need to be attenuated zero before next applied. As result, has simpler start-up procedure and can applied cases such as loaded uninterrupted restart. A phase-locked loop (PLL)...
Permanent magnet assisted reluctance (PMAREL) machine possesses a promising application prospect in the aircraft starter/generator (S/G) system. This article presents high-performance generation control strategy for dual-three-phase (DTP) PMAREL S/G By studying DTP models synchronous frame, framework suited is provided, which consists of current-control inner loop and voltage-control outer loop. For current control, negative effects magnetic saturation on conventional method are studied. To...
