This paper presents a novel sensorless drive method of the Axial flux permanent magnet (AFPM) brushless direct current (BLDC) motors by detecting zero-crossing points of back electromotive force signals from the standstill state to the desired velocity. A soft-switching mechanism is combined with the sensorless drive approach to achieve low electronic noise(More)
When viewing three-dimensional (3D) images, whether in cinemas or on stereoscopic televisions, viewers experience the same problem of image brightness loss. This study aims to investigate image brightness loss in 3D displays, with the primary aim being to quantify the image brightness degradation in the 3D mode. A further aim is to determine the image(More)
In this study, we propose a current-sensor-based predictive current control (CSBPCC) for six-switch three-phase (SSTP) inverter-fed synchronous reluctance motor (SynRM) drives. Generally speaking, two current sensors are used for detection of a- and b-phase stator currents of a SynRM drive system, respectively. In each sampling interval, the stator current(More)
