Herbert Hess' research is in the area of power electronic converters, great and small. These range from projects in wind turbine converters to motor drives to small power supplies to microbattery chargers. Each system has a need for converting power into a different form or level. Power electronics is often the preferred means to do this.

Hess' ongoing projects are the following:

• Power conversion circuits in CMOS SOI
• High voltage CMOS silicon on insulator (SOI) switching devices
• Hybrid electric vehicle power conversion and drive systems
• Modeling and design of protection for matrix converters
• Innovative and compact battery chargers and monitors
• Distributed power generation and electronic conversion: wind, water, fuel cell, solar, flywheel
• Power quality

• UPS battery cycle extension
• Submarine propulsion power: motor drives, instrumentation, quality of shipboard and shore power, battery charging
