Constant current supply system for a variable resistance load |
摘要 |
A constant current supply system for a variable resistance load includes first and second output terminals for applying a predetermined current to a variable resistance load; a constant current circuit connected to the second output terminal for providing the predetermined current to the load; a voltage supply connected to the first terminal for providing a voltage across the terminal and constant current circuit; and a voltage supply control circuit for monitoring the voltage at the second terminal across the constant current circuit and adjusting the voltage supply to maintain the second terminal at a preselected voltage for maintaining the predetermined current to the variable resistance load.
