The applications of bidirectional full-bridge DC-DC isolated converter in UPQC

The conventional methods used in the isolation of the UPQC are add a isolation transformer in the point, in which series unit or parallel connection unit access the system, but owing to the non-linear of the transformer, this isolation method shall bring many baleful ingredients. In order to avoid the baleful influence of the conventional isolation transformer, the text introduces a sort of new-style single-phase UPQC structure, base on UPQC isolated in the direct current side.
