The Medium Voltage Power Electronics Laboratory (MVPEL) at NCPRE, IIT Bombay, is a pioneering facility and the first of its kind in India, established to foster cutting-edge research in MV power electronics. Designed to meet the growing demand for advanced MV systems, this laboratory offers a unique infrastructure for designing and developing innovative solutions in power electronics. The facility, set up with the support from MNRE, is equipped to support research in PV central inverters, direct MV grid-connected inverters, high-power converters, high-voltage device characterization, and HVDC systems, positioning IIT Bombay as a leader in this domain. The laboratory is equipped with advanced instruments capable of handling voltages ranging from 0 to 11 kV AC and power levels up to 200 kVA. Its key resources include a grid simulator (400 V, 22.5 kVA) to emulate grid conditions, MV DC power supplies rated at 6 kV and 10 kV, and high-precision measurement tools such as high-bandwidth oscilloscopes and optically isolated highvoltage probes (2.5 kV). For higher voltage applications, the lab also utilizes passive high-voltage probes capable of measuring up to 20 kV. This comprehensive suite of equipment enables the precise characterization and testing of MV systems and components, offering unmatched capability in the Indian research landscape. The lab setup is engineered with a high emphasis on safety and operational flexibility. The setup includes High Tension and Low-Tension panels, auto-transformers, and step-up transformers, providing a robust infrastructure to facilitate diverse testing requirements. The well-organized layout ensures efficient workflow and seamless integration of equipment during experiments, making it ideal for both academic research and industry collaborations.
