This method does not depend on the level of static load and on any motor parameters. Also the magnetic pole is identified utilizing the effect of magnetic saliency.","PeriodicalId":201844,"journal":{"name":"APEC 2001.

The behavior of PTs is very dependent on the material type, geometry and number of layers. Since PTs should be used in a power topology, it is necessary to establish design rules in order to select the proper specifications of the PT for each particular application. This work presents some design guidelines as well as the description of the influence of several constructive parameters on the behavior of the multi-layer PTs.","PeriodicalId":201844,"journal":{"name":"APEC 2001.

Several works have been done concerning the optimization of the electrical and magnetic design. However, the thermal design of these components has not been studied deeply, and less information is available to predict the temperatures in core and windings of the component during the design stage. This paper addresses such issues for stand alone planar magnetic components and those with windings integrated in the printed circuit board (PCB). Thermal dissipation methods, models and several experiments are described. They allow a better thermal calculation of the planar magnetics components in the early design stage.","PeriodicalId":201844,"journal":{"name":"APEC 2001.

VR actuator does not have a permanent magnet. It is low-cost, easy-to-manufacture, highly reliable and can operate in hostile temperatures. However, it is inherently nonlinear, and is difficult to control and operate as a proportional device. With the advancement of digital signal processing and power electronic drives in recent years, VR actuators have redrawn research interests. The paper describes the investigation and development of a novel two-finger gripper using VR technology. A novel two-finger VR gripper is proposed and fabricated. Measurement and characterization of the actuator is carried out and a mathematical model of the actuator is constructed. Finally, model is simulated and it is verified with experimental results. The actuator exhibits pseudo-linear properties and it is suitable for position and force control applications. The results show that the proposed actuator is an ideal replacement for the higher-cost and less-robust permanent magnet actuators.","PeriodicalId":201844,"journal":{"name":"APEC 2001.

However, for online system stability monitoring, directly measuring impedance of the source and load subsystems then making comparisons is too complicated and difficult. This paper proposes practical and simple methods, which involve applying current or voltage perturbation to the DC side of distributed power systems then only measuring the amplitude of two currents or voltages in order to monitor the stability margin. For both methods (current perturbation and voltage perturbation), an implementation approach that does not employ external voltage perturbation source is also presented. A comparative evaluation of each method and its corresponding implementation approach is provided.","PeriodicalId":201844,"journal":{"name":"APEC 2001.
