In Reply to: what would you do? posted by MtBiker on May 7, 2002 at 20:16:45:
I would do exactly what I suggest:
find a used super amp, with a reputation for good drive capability, with enough rated power to the volts, and amps (in bridged mode) and handle the reactive load.I was assuming the use of a low distortion sine wave osicllator circuit, tuned as precisely to 60 Hz as possible.
This route will be cheaper, quicker, and less subject to unpleasant surprises.
However, if you insisted on designing and building such a "low watt" power isolator, then I might look at a very simple Class B high voltage, high peak current power amp design, with low long term capacity, which means you can skimp on heat sink, and use less output transistors than an amp along the lines of what I was recommending.
Depending on what you were trying to achieve, a nice mondo isolation transformer, or a balanced power transformer might be the way to go.
