Welcome to Sustainable Power Electronics Laboratory

Welcome to Sustainable Power Electronics Laboratory

SPELL (SUSTAINABLE POWER ELECTRONICS LAB) is a state-of-the-art Power Electronics facility at the Indian Institute of Science, where futuristic technologies are developed and transferred to relevant industries. In power electronics we process electric power through SEMI-CONDUCTOR SWITCHES. These power devices (MOSFET or IGBT) are at the heart of any power electronic converter. In many of our work we try find new topologies (configuration of switches) and modulation strategy (switching scheme) that improve power conversion efficiency and reduce size and cost. We emphasize on DESIGN, FABRICATION & TESTING of state-of-the-art and advanced POWER CONVERTERS. We do work on cutting edge embedded solutions for power electronic applications.


Here are a few applications that we are currently working on

Grid integration of Renewables

In power electronics we process electric power through semi-conductor switches. These power devices (MOSFET or IGBT) are at the heart of any power electronic converter. 

Powering Electric Vehicles

Electric Vehicles (EV) pose a wide range of challenging problems to the power electronic engineer. In EV basically we drive an electric motor (Engine) from a battery (Fuel).

Medium Voltage Power Electronics

Power electronics research witnesses the emergence of medium voltage solid-state transformers, a transformative area that enables direct interaction with medium voltage 

Space Power Electronics

Satellites are primarily powered by solar energy and hence require power converters to supply the onboard loads. We are working with ISRO to develop a high frequency

Next Generation Devices

Wide band gap semiconductor (WBG) devices such as GaN and Silicon Carbide are going to replace currently used silicon based power MOSFET and IGBT, due to their low conduction and switching

Embedded system developement
