- I'm trying to find out if what I'm planning to do has been done before.
- I want to use 100VDC to power an incandescent lamp circuit, that will
- drive regular light bulbs with sine waves in the frequency range of 1HZ
- to 30HZ. The sine waves will be +VDC offset, so that the most negative peak
- of the sine wave corresponds to 0VDC. The amplitude should be controllable,
- but that can be sacrificed in the early versions of the circuit.
-
- If this has been done before, I'd like some reference information. I'm
- looking for design hints and constraints.
-
- Thanks!
