Various types of switches are widely used in aerospace automatic test industry, such as toggle switch, tree switch, mux switch and matrix switch etc. Different types of switches have different drivers and development methods. To simplify the implementations of drivers and reduce the cost and time associated with developing new test systems. This paper proposes a universal model to define different...
There are many costs associated with the building and running a telecommunications network, both capital (CAPEX) and operational (OPEX) costs. On the one hand, complex routing schemes activated in multi-layer networks, like MPLS, logically imply assignment of costs to a collection of modules, from more than one layer, so defining the cost model is a non-trivial task. On the other hand, optimization...
To evaluate the performance of IEEE1588 synchronous system efficiently, and configure the operating parameter of the system, this paper designed a performance evaluation system of IEEE1588 synchronization system. The method adopting network communication is used to observe the real-time offset information and its statistical parameters. Moreover, the operating parameters can be configured through...
The Reconfigurable Smart Sensory Chip (RSSC) is a powerful tool for fast prototyping sensory microsystems. Innovative design ideas can be quickly realized and tested in hardware without doing time-consuming and expensive silicon fabrication. The RSSC is a large-scale floating-gate based IC containing 8 universal sensor interface blocks, each of which can be configured for voltage sensing, capacitive...
In this paper, an AC current sensorless control scheme of three-phase PWM rectifier is proposed. A method for reconstructing the AC currents from the DC-link current and switching state is given. A method of modifying the switching state of PWM rectifier is given when the input currents cannot be reconstructed. The control system based on SVPWM includes two PI controllers which are used to regulate...
