REGENERATIVE POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To shorten a response time of a regenerative power supply device.

SOLUTION: In a regenerative power supply device 100a, a bidirectional DC-DC converter 1 is connected between an AC-DC converter 2 having a regenerative function and a specimen 3 capable of being bidirectional energization. A comparator compares a specimen voltage with a set voltage. A first clamp circuit 20 compares an output voltage of the comparator with a voltage corresponding to a set power running current and sets the output voltage of the comparator as an upper limit clamp so as to apply a voltage that supplies the set power running current to a specimen 3 to the bidirectional DC-DC converter 1. A second clamp circuit 30 compares the output voltage of the comparator with a voltage corresponding to a set regenerative current and sets the output voltage of the comparator as a lower limit clamp so as to apply a voltage that absorbs the set regenerative current from the specimen 3 to the bidirectional DC-DC converter 1.
