Asymmetric Limit Cycles in an Industrially Applied Controlled Resonant Converter

An industrially applied LCC power converter is modelled as a hybrid system. It is found that the hybrid system given a parameter set up and different initial conditions has three different limit cycles, one unstable and two asymmetric stable limit cycles. Effects of the asymmetric limit cycles are considered.

Improving Laboratories with Internet Controlled Equipment and Student Support

The engineering laboratory equipment at UTC has been made available for users via the World Wide Web. Users can conduct systems lab experiments from remote sites, anytime day-or-night, any day of the week. With remote access, students need support in a different manner than with traditional laboratory courses. This paper discusses aspects of this situation and suggests ways to accomplish this s...
