摘要：
On-load tap changing transformers play important roles in any modern power system, since they allow voltages to be maintained at desired levels despite load changes. Traditionally, on-load tap-changer is a complex mechanical device, which has some deficiencies. In this paper, a new scheme for on-load tap-changer of transformer is presented, which can eliminate excessive conduction losses and suppress the arcing in the diverter switch, which are inherent in traditional on-load transformer tap-changers. The presented on-load tap-changer has the different circuit configuration and operation principle from the traditional tap-changer. Besides, the results of simulations and experiment are given, showing that the proposed on-load tap-changer is feasible.
