Power Electronics Lab

Many new equipments were procured for Power Electronics Lab which was set up successfully. Some of the equipments include Slide Wire Potentiometer, Vernier Potentiometer, Spot Reflecting Galvanometer, and LVDT. Experiments on Bridge Converters, Triac, PLL, Thyristors are carried out and waveforms are observed on digital oscilloscopes.
