Interactive learning for waveform dynamics of diode rectifiers and RC filter in DC power supply

Electronics Students have always been struggling to understand the voltage waveform dynamics across different points in diode rectifiers, which leaves them confused and the grasp of DC power supply is always missing in their understanding. In this paper, we present Scenario-based e-learning product dasiaDC Power Supply Simulatorpsila developed using Macromedia Flash for an introductory technology course. This product is developed at the university to help students to understand the complicated concepts such as diode rectifiers, voltage dynamics of power supply, RC filter, etc. This DC-Power Supply Simulator consists of various components such as transformer, diodes, resistor and capacitor. The simulator strongly supports the visualization of the dynamics of the circuit while a user manipulates its parameters. The voltage waveforms at different places in the circuit are dynamically plotted in realtime as in an oscilloscope, a strong feature of this simulator.
