Voltage unbalance is a power quality problem of significant concern at the electricity distribution level. An excessive level of voltage unbalance can have serious impact on mains connected induction motors. The level of the current unbalance that is present is several times that of the level of the voltage unbalance. Such unbalance in the line currents can lead to excessive losses in the stato...

Whenever devices are operated in parallel, due consideration should be given to the sharing between devices to ensure that the individual units are operated within their limits. Items that must be considered to successfully parallel MOSFETs are: gate circuitry, layout considerations, current unbalance, and temperature unbalance. This application note covers these topics and provides guidelines ...

Sensory input plays an important role to human posture control system to initiate strategy in order to counterpart any unbalance condition and thus, prevent fall. In previous study, joint stiffness was observed able to describe certain issues regarding to movement performance. But, correlation between balance ability and joint stiffness is still remains unknown. In this study, joint stiffening ...

Voltage Unbalance is a common type of power quality problem. Sequence components occur during unbalance in three phase system. For this reason unbalance is assessed with respect to the sequence components present in the system. Voltage unbalance may adversely affect power system components connected to the system. In this paper, for symmetric and asymmetric faults, positive sequence voltage is ...

An aero engine fan rotor is composed of a multi-stage disk and blades. Excessive unbalance the after assembly main cause vibration. In process, blade sequencing optimization set phase are important for reducing overall unbalance. To address this problem, paper proposes semi-physical simulation method based on reinforcement learning to optimize balance in process. Firstly, mass moments individua...
