costs less, and most of the industrial motors make use of AC power. See Figure 10 for acomparison between AC and DC currents. Figure 10: Graph of AC current (sine wave) vs. DC current (flat line). This activity however, used DC power for several reasons. First, AC power systems mustbe synchronized and achieving this on a small grid would be very difficult. Second, the loads onthe system will be LEDs (light-emitting diodes), which require DC electric current. This activitywas an end-of-the-year project which was conducted over many days. Students were first askedto design/build their own wind turbines out of cardboard. When this process was complete, theybuilt a power grid using wires and LEDs, which was setup to utilize DC

. Poor agreement between the refrigerant-side and air-side measurementsshowed the instruments needed to be calibrated or replaced. Second, the overall heat transfer coefficient (U) for the selected operating condition wasdetermined. The data from the experiment was fed into a computer analysis program developedby an upperclassman as part of an independent study project. The program calculated the finefficiency to adjust the area of the fins to an equivalent area. The overall heat transfer coefficientwas a key input into the system model which the thermodynamic students then used to performthe optimization. 4 2

During his college career he worked four summers at U.S. Steel as an assistant electrician, rewinding motors and installing electrical equipment. He served 21 years in the U.S. Air Force, including six years designing, constructing, and inspecting electric power distribution projects for a variety of facilities. He spent five years teaching and researching pulsed power systems
configurations to achieve proper phase shifts. Open-circuit and short-circuit tests.The first six experiments were also done in fall 2013. Experiment #7, on three-phase transformerconnections, was only done in fall 2014 and it will be performed in the new hardware lab startingin fall 2015. Based on a summer 2014 senior design project, and using single-phase transformersthat were salvaged from the old lab, we are constructing new transformer banks on carts withwiring panels to support this experiment #7, and also to support research in the lab. This was themost complicated and lengthy software experiment, and will work better in the hardware lab.Figure 4: Finite Element Based Actuator Model Interfaced to a Drive Circuit and LoadFigure 5: Brushless
