The rationale for this initiative was to provide students with a scalable and risk-free environment to perform com plex power converter and switching device experiments that might be challe nging or costly to conduct using physical hardware.\nThe session aimed to enhance the students understanding of theoretical concepts by allowing the m to observe the real-time behavior\, transient responses\, and performanc e characteristics of various power electronic circuits under different ope rating conditions.\n\nThe V-Lab session was structured to be highly intera ctive and hands-on. Each experiment was initiated with a brief theoretical review followed by a guided demonstration of the V-Lab interface. Student s were provided dedicated system access to individually perform the experi ments\, record readings\, and analyze the resulting waveforms.\nThe sessio n covered fundamental and advanced concepts in power conditioning and cont rol\, allowing students to systematically study components and systems cen tral to modern power engineering applications.\n\nSome experiments from th e Power Electronics domain were successfully covered during the virtual la boratory session which includes:\n\nCharacteristics of Controlled Switchin g Power Devices: This experiment focused on determining the static and dy namic operating characteristics of critical power semiconductor switches ( e.g.\, SCR\, MOSFET\, IGBT)\, which are the fundamental building blocks of all power converters.\nPerformance Measurement and Analysis of Single-pha se AC-DC Controlled Bridge Rectifier: Students analyzed the input current and output voltage waveforms\, power factor\, and harmonic content of a si ngle-phase half-controlled or fully-controlled bridge rectifier circuit.\n Performance Measurement and Analysis of Non-isolated DC-DC Boost Converter : This involved studying the operation of a step-up converter to understa nd the relationship between duty cycle\, input voltage\, and the magnified output DC voltage.\nPerformance Measurement and Analysis of Single-phase AC Voltage Controller: The experiment focused on controlling the AC output voltage applied to a load by varying the firing angle of the Triac/SCRs\, analyzing its effect on RMS output voltage and harmonics.\nSingle-phase I GBT Inverter under Sinusoidal PWM Control: Students implemented and analyz ed the output voltage control and harmonic reduction capabilities of a sin gle-phase inverter using Sinusoidal Pulse Width Modulation (SPWM) techniqu es.\nThree-phase IGBT Inverter under Sinusoidal PWM Control: This extended the concept to a three-phase system\, allowing students to generate balan ced three-phase AC output voltage with control over both frequency and mag nitude.\nPerformance Measurement and Analysis of Isolated DC-DC Flyback Co nverter: This specialized experiment allowed students to explore the use of a transformer for isolation and voltage control in a switched-mode powe r supply topology.\n\nThe virtual lab session successfully provided the 5t h-semester EEE students with crucial practical exposure to the behavior an d analysis of complex Power Electronics circuits\, thereby significantly e nhancing their conceptual clarity on topics like pulse-width modulation (P WM) control\, converter operation\, and switching characteristics.
