Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

1. Field-oriented control (FOC), also known as vector control, maintains a constant stator field in quadrature with the rotor field irrespective of any bandwidth limitations presented by the PI ...

The past few decades have seen a rise in the use of field-oriented control in induction motor applications. One advantage of field-oriented control - The past few decades have seen a rise in the use ...

Over the last decade, there has been a move away from powered-up digital in-circuit vector testing to unpowered analog-based (vectorless) device-pin opens testing for large and sometimes small digital ...
