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).
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
