ABSTRACT:
A supply circuit for a load which is to be continually supplied within a projectile, with a generator connected ahead of a voltage generator, in particular a thermo-generator, which provides a power output which increases to a maximum within a first supply stage of the load and drops off in a contiguous second supply phase of the load, whereby during the first and second supply phases the provided power output is greater than the power required for the operation of the load. The load and an RC-charging circuit with a storage condenser are located in parallel at the voltage generator output so that during the first supply phase of the load there will charge the storage condenser wherein a diode is connected into the RC-charging circuit so as to prevent the discharge of the storage condenser during the second supply phase, and in which a switch controlled by the output voltage of the voltage generator is connected between the storage condenser and the load, which is blocked during the first supply phase and which is actuated as soon as the output voltage of the voltage generator has reached a value in which is insufficient for the operation of the load, whereby in a third supply phase the load is supplied through the switch from the storage condenser.
