Communication Power Laboratory
Located in the Communications Power Laboratory, founded in 1999, the Queen's Power Group includes one full-time faculty member, Dr. Yan-Fei Liu, and several graduate research assistants.
The Queen's Power Group focuses on research for the telecommunications and computing industries. Our areas of expertise include:
- Digital control techniques to achieve optimal dynamic performance
- High efficiency, low voltage, high current DC-DC converters
- High switching frequency converters
- Soft switching techniques
- Current source MOSFET driver techniques
- Power Factor Correction (PFC) techniques
- Electromagnetic compatibility and EMI filters
- Magnetic component design
- Computer simulation and computer aided design of converters
Our aim is to develop new techniques in digital control theory, power converters, voltage regulators, power factor correction (PFC), electromagnetic interference (EMI) filters and magnetic components.
Our group provides training in hardware design, computer simulation and analytical design approaches for both graduate and undergraduate students. Combined with a solid background in modern control theory, this training allows graduate researchers to prosper in the vast field of power electronics.
Our facilities include an up-to-date power electronics laboratory and computing laboratory. The power electronics laboratory contains the latest network, spectrum and impedance analyzers, digital oscilloscopes, power supplies and electronic loads. Our computing laboratory includes laptops for students and two Sun workstations. We utilize the latest simulation and analysis tools including Matlab, MathCAD, Simetrix Spice, Analog Workbench, Simplis and Protel. In addition, DSP and FPGA development tools are equipped for the design of mixed-signal integrated circuits systems, which combine power stages with microprocessors.
