The dual three-phase permanent magnet synchronous generator (DTP-PMSG) has a promising application in aircraft starter-generator system. However, the electromagnetic coupling existing between three phases causes current harmonics, which poses difficult problem for highly dynamic voltage stabilisation control of DTP-PMSG. In this paper, maximum four-vector space vector pulse width modulation (SVPWM) algorithm is proposed based on decoupling (VSD) to achieve harmonic suppression DTP-PMSG...
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...
Interior permanent magnet synchronous motor (IPMSM) systems are vulnerable to uncontrolled generation (UCG) when the inverter switches loss their drive signals suddenly during field weakening high speed operation. At this point, rectifier-like is composed by six freewheel diodes, current comes from through and converter, then charges battery. This paper develops a simple analytical model of system firstly, carries out simulation UCG transient process in with boost DC/DC buck-boost...
Frequency-domain impedance or admittance model is widely applied to analyze the harmonic stability of power electronic converters. Conventionally, converter modeled holistically, without exhibiting sole effect different control and phase-locked loop (PLL). Besides, voltage current injection external usually adopted, which involves dedicated equipment introduces unexpected inner impedance. In this article, response perturbation upon ac–dc converters along various signal flow paths analyzed,...
In this paper, we study the minimum feedback rate of time-correlated MIMO block-fading channels when water-filling precoder is applied at transmitter side. Unlike previous work, impact both channel estimation errors and quantization distortion taken into account. With backward-channel transmission constraint, in periodic system, further analyze relations between ergodic capacity cycles. We found that there exists an optimal cycle terms given constraint.
In this paper, the thermal performance of an all SiC 650 V, 116 A MOSFET power module has been studied by numerical simulation.Aiming at heat dissipation problem devices in inverter, three integrated liquid cooling sinks with different channel structures were designed.The results showed that compared other two structures, serpentine flow structure can provide best effect.For structure, source maximum temperature increases as fin thickness increases, and pressure drop decreases increase when...
