An Active Power Factor Correction Laboratory Experiment for Power Electronics CourseAbstractThe use of power factor correction (PFC) circuits has been proven to save electrical energy useby up to 25%. When electrical loads are predominantly linear, a simple shunt capacitor willgenerally be sufficient to improve the power factor. However, as the use of power electronicsbecomes more prevalent, a more advanced solution using active components is needed. Onesuch active PFC circuit currently installed in today’s off-line switching power supplies such asthose used in personal computers is the boost-converter based active PFC. Such an increasinguse of active PFC demands an understanding of its concept and operation for future powersupply engineers. This paper presents a new laboratory experiment that was developed toenforce student’s understanding of boost active PFC. The experiment consists of computersimulation and hardware setup enabling students to inspect and observe the benefits of usingactive PFC as compared to two conventional methods. Moreover, the hardware setup for the labexperiment uses a module that was built in a simple way such that it can be easily replicated.The newly developed active PFC experiment has been introduced to our students for the pastthree years. Lessons learned from running this experiment including ideas for furtherimprovement of the experiment will be discussed and presented in this paper.
