A strong mission of the UCI laboratory is to contribute to the success of our
industry by providing the latest technology and excellent students. In
the mean time, our program relies on support from industry to survive
and grow. The following is a list of research areas that may be suitable
Power Factor Correction (PFC) methods for single phase and three phase
rectifiers (simple analog control circuit, high reliability, suitable for
- Passive and active lossless snubbers for converters and inverters
(any converter topology, reverse recovery control, solve shoot-through
problem, reduce heatsink, increase efficiency).
- High fidelity class-D power amplifier (does not need regulated DC
supply, 20kHz bandwidth, 0.07% maximum THD+N measured under 15%power
supply ripple condition, no need to match the switching components, good
for massive production).
- Cross regulation of switching power supply with multiple outputs,
simple and passive circuit with no/low additional cost.
- Active power filter to achieve unity power factor and low harmonic
distortion with a simple one-cycle control based analog control circuit.
(suitable for a large system, one filter at the input will fix the input
current of the whole system).
- Power conversion for alternative energy sources, such as solar cells,
fuel cells, fusion reactors, wind power, etc.
- Current pulse power supplies for laser applications.
- High efficiency power supply design.
The Power Electronics Laboratory at University of
California, Irvine, is a modern research facility.
It is equipped with the state-of-the-art
instrumentation for design, simulation, layout,
prototyping, and testing of switching converters
and analog/digital circuits. The research in the
Power Electronics Laboratory at UCI involves
modeling, control, topologies, and integration of
switching converters, inverters, class-D power
amplifiers, soft switching techniques,
single-phase and three-phase power factor
correction methods, power conversion for
alternative energy sources, etc.
