Instrumentation for Contemporary Energy Conversion Teaching Laboratory

电子技术的最新发展，例如引入成本相对较低的功率开关设备和易于应用的微处理器，正在导致电力电子转换器和控制器的广泛采用。因此，电能转换教育的重点必须适应这些变化。本项目拟将当代展示与记录技术引入本科课堂。对于主观暴露于高谐波含量的电压和电流现象，需要电流探头忠实地响应从直流到高频的信号，以及适当的示波器用于显示，捕获和存储。测量真正的有效值现在需要特殊的仪表正确响应非正弦交流和扭曲的直流分量。最后，需要基于霍尔效应器件的传感器进行测量，以确定真实功率和功率因数。这个项目的目的是为本科生提供在这个快速变化和非常重要的领域的实践经验。

Recent developments in electronics, such as the introduction of relatively low cost power switching devices and readily applicable microprocessors, are resulting in the widespread adoption of power electronic converters and controllers. Consequently the emphasis of electrical energy conversion education must adapt to reflect these changes. This project proposes to introduce contemporary display and recording techniques to undergraduate classes. For subjective exposure to the phenomena of voltages and currents with high harmonic content, current probes which respond faithfully to signals from dc to high frequency are required, together with appropriate oscilloscopes for display, capture and storage. Measurements of true r.m.s. values now require special meters which respond correctly to non-sinusoidal ac and distorted dc components. Finally, transducers based on Hall-effect devices are needed for measurements to determine true power and power factor. It is the aim of this project to provide undergraduates with hands-on experience in this rapidly changing and highly important area.
