定電力負荷装置
Document Type and Number:
Japanese Patent JP4052824
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a constant-power regulated load device which provides high-accuracy constant-power loads in a simple circuit configuration. SOLUTION: The constant-power regulated load device comprises a voltage conversion circuit 4, a current control circuit 5, a current conversion circuit 6, and an integrated control circuit 7. The voltage conversion circuit 4 divides the voltage of an electric power source being tested 1 and outputs a differential voltage V1 between the divided voltage and a predetermined reference voltage. The current control circuit 5 controls the current of the electric power source 1. The current conversion circuit 6 outputs a voltage V2 in response to the current controlled by the current control circuit 5. The integrated control circuit 7 controls the current control circuit 5 so that the voltage V1 output by the voltage conversion circuit 4 and the voltage V2 output by the current conversion circuit 6 coincide.
