Welcome to Renewable-energy Interface and Grid Automation (RIGA) Lab

Renewable-energy Interface and Grid Automation (RIGA) Lab is a research lab at the University of Manitoba which was established by Dr. Carl Ho. The establishment of the lab was funded by the CFI in Oct. 2014. And it has been completed in April 2016 and renovated in February 2019. Currently it is located at the room E1-468B. The lab is mainly to develop power electronics technologies for renewable energy and smart grid applications.
