hi friends,
Do you have an idea or circuit for "AC square wave constant voltage generator" with short circuit protection ? The spec: 1. The square wave output is 24v 200mA. 2. Max load's resistance is 8000 ohm 3. When the load's resistance is decreased,the current will drop to a value but the voltage always keep 24v. I have no idea how to keep 24v.
The frequency must be fixed between 100hZ and 100khZ.
... we could also ask whether this is really AC - ie alternating - or is it just pulsed DC?
ie, does the voltage swing between +24V and -24V (or +/-12V), or is it just 0V and 24V?
