Abstract:
In combination with a load circuit and a voltage supply, a circuit configuration for supplying the load circuit with a high voltage having a value greater than a value of the voltage supply supplying the circuit configuration, the circuit configuration comprising:a pump circuit having a high voltage output electrically connected to the load circuit for outputting a high voltage to the load circuit;the voltage supply outputting a voltage with a value to said pump circuit;an electronic control circuit connected to said pump circuit and receiving a voltage derived at least from the voltage supply; anda control signal derived in dependence on the value of the voltage supply received by said electronic control circuit, said electronic control circuit in dependence on said control signal emitting a switching signal having a pump frequency to said pump circuit for controlling a generation of said high voltage output by said pump circuit, a value of said pump frequency is inversely proportional to the value of the voltage supply.
