Rather than throw his old TV set away, Mark turned it (along with a few other parts) into a power supply for a plasma globe. Basic construction of the device is a flyback transformer with primary, feedback, and secondary coils. Acting like an inductor, the flyback is wired so that the feedback winding fires the gate of a transistor, which turns the primary winding off and induces current in the secondary winding. The secondary winding and plasma globe form an LC circuit that operates at its resonant frequency (20 to 30 kHz).
Plastic may not be the most beloved of materials to the more environmentally minded, but Plasti 2012 aimed to mold a different opinion of the material in people's minds.
The rare earth element market has become steadily more rational, and new sources coming online will continue to reduce costs. Still, it is unlikely that prices will drop to their former lows.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
