Power electronics is the technology that ties wind turbines and photovoltaics to the electric power grid, propels hybrid and electric vehicles, powers a countless variety of electronic systems, and makes it possible to operate battery-powered mobile devices for many hours. In the Colorado Power Electronics Center, we are exploring ways to achieve significant system-level advances in energy efficiency and renewable energy sources via smart power electronics. Current research project topics include:

• Digital control for improved efficiency and improved transient responses in high-frequency switched-mode DC-DC power converters
• Auto-tuning and adaptive control techniques for switched-mode power converters
• Digital control for improved efficiency and reduced harmonic distortion in AC-DC power factor correction rectifiers over wide ranges of operating conditions
• A/D and digital PWM techniques for mixed-signal power control and power management integrated circuits
• Power management for high-efficiency handset and base station RF transmitter systems
• Plug-and-play smart DC power systems
• Automotive power electronics, battery systems, and grid integration of electric drive vehicles
