Spotlight Q&A: Dr. Subhashish Bhattacharya

July 16, 2018

Dr. Battacharya recently talked with FREEDM industry member Typhoon HIL and discussed how Controller Hardware-in-the-Loop (C-HIL) reduced the cycle time of design, validation, and testing of DC Microgrid controllers from academia to industry.

Smart Transformers Will Make the Grid Cleaner and More Flexible

June 29, 2017

It would be hard to overstate the importance of transformers in our electrical networks. They’re literally everywhere: on poles and pads, in substations and on private property, on the ground and under it. There are probably dozens in your neighborhood alone. It’s hard to imagine a world without them. But Subhashish Bhattacharya and his colleagues are doing just that.

Software Regulates Voltage in Everyday APUs

September 16, 2015

NC State researchers have created software that manages all voltage regulation in an embedded system solely on the applications processor unit (APU), without resorting to expensive smart switch-mode power supplies (SMPSes) with their own microcontroller or application processors with higher-speeds than necessary just to ensure proper performance. Alexander Dean and Subhashish Bhattacharya, electrical & computer engineering, featured.
