The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...

One of the greatest attributes of metal halide perovskite solar cells is their surprisingly low loss in potential between bandgap and open-circuit voltage, despite the fact that they suffer from a nonnegligible density of sub gap defect states. Here, we use a combination of transient and steady state photocurrent and absorption spectroscopy to show that CH3NH3PbI3 films exhibit a broad distribu...

Safe operation of electric motor drives is of prime research interest in various industrial applications. This paper presents a new fault diagnosis system for open circuit switch faults in three phases Voltage Source Inverter (VSI) drive of the permanent magnet Brushless DC (BLDC) motors. The proposed fault diagnosis system is capable of detecting as well as identifying the faulty switch in the...

However, they have low open-circuit voltages and typically cannot be made optically thick while maintaining high fi ll factors. [ 4,5 ] For comparison, the best silicon solar cell has a bandgap of 1.1 eV and an open-circuit voltage of 0.71 V, corresponding to a difference between the bandgap and qV oc of only 0.40 eV. [ 1 ] In contrast, one of the best performing organic solar cells, PTB7:PC 71...

In this paper, a test circuit for a test method is proposed, with which open leads of CMOS logic ICs are detected without generating test input vectors. Open leads are detected by means of supply current of the test circuit that flows when an AC voltage signal is provided to targeted leads with test probes as a stimulus. It is examined by some experiments whether open leads will be detected wit...

We investigate the quantum photovoltaic effect in double quantum dots by applying the nonequilibrium quantum master equation. A drastic suppression of the photovoltaic current is observed near the open circuit voltage, which leads to a large filling factor. We find that there always exists an optimal inter-dot tunneling that significantly enhances the photovoltaic current. Maximal output power ...
