This discussion focuses on achieving a parallel circuit with a variable voltage constant current power supply capable of delivering 0-300V at 50mA on one side and 0-300V at 50µA on the other. The proposed solution involves building a 0-300V 50µA constant current regulator, as a simple resistor will not suffice due to the supply's maintenance of 50mA. Active components are necessary to create the desired current regulation, with minimal power dissipation of 15mW when shorted.
PREREQUISITESElectrical engineers, hobbyists designing power supply circuits, and anyone involved in high voltage electronics who needs to implement precise current regulation.
...and so is worth pursuing. Thank you very much. your help is much appreciated. It will save me having to purchase another power supply.meBigGuy said:Build a 0-300V 50uA constant current regulator. The main supply will just sit at 300V trying to drive 50ma.
There is no way that occurs to me to do it without active components. It only needs to dissipate 15mW when shorted and the input is 300V.
