Abstract—Generally, regeneration occurs in an AC variable frequency drive system when the load overhauls the motor. In this paper, it is proposed the scheme of energy efficiency improvement in 48V multi-axis robot system with a frequently accelerating and decelerating operation patterns that can cost-effectively use the regeneration energy and also minimize DB from the system. As a result, it is shown that the proposed method is used to develop the extra power from the expanded regeneration section over the conventional method and the effectiveness is proved thorough the developed topology of FCC and experiment result.
