Director’s Welcome


Welcome to the Center for High Performance Power Electronics (CHPPE) at The Ohio State University. Our world-class power electronics laboratory was established thanks to a $9.1 million grant from the Ohio Third Frontier Initiative, national lab and industry partners.

The research at CHPPE is focused on harnessing the strengths of wide band gap (WBG) devices, currently created from Silicon Carbide (SiC) and Gallium Nitride (GaN), in emerging power electronics applications.  These devices have ability to operate at higher temperatures, switch at faster speeds, and achieve better efficiency over their Silicon (Si) based counterparts.  The WBG technology allows designers to realize smaller, more efficiency hardware, as well as develop power electronics for new applications in the aerospace, auto, and utility industry.

CHPPE houses an advanced hardware-in-the-loop (HIL) testing platform and current work includes investigating the impact of communication delays on the stability of the smart grid, and device, circuit, and complex system modeling.

The center currently has 5 faculty members, 4 visiting scholars, and 35 graduate students who are involved in different aspects of power and energy technologies, including:

  • Semiconductor Fabrication, and Device Design
  • High Power/High Voltage Power Electronics
  • Electric Machines and Motor Drive Technology
  • Power Distribution Systems and Smart Grids
  • Real Time Simulation, Hardware-in-the-Loop, and Power-in-the-Loop

CHPPE is a multidisciplinary research and education center dedicated to training and educating the future generation of power electronics and systems leaders.  It will evolve from its current aerospace centric capabilities into a research facility that will serve all industries, including electric utility companies, military organizations, and Original Equipment Manufacturers of power electronic related goods.
