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.
Additionally
24 V on 800 ohm get 30 mA so you have to check your specification. For 800 ohm load you need at least a generator with 160 V.
For a simple on/off a switched constant current generator can do the job (the frequency can be the problem if too high).
You are an order of magnitude off. The specified load was 8 kohm, not 800 ohm, so it would take 1,6kV to drive 200mA through the load, and the power sent into the load would be 320W at 50% (?) duty cycle.
