Zusammenfassung:	A power expanding apparatus for three-phase LLC circuit is disclosed, which includes full-bridge switching networks, resonant networks, transformer networks, and rectifying networks. A primary side of a first transformer network is connected with an input voltage sequentially through a first resonant network and a first full-bridge switching network, a secondary side of the first transformer network is connected with a load through a first rectifying network; a primary side of a second transformer network is connected with the input voltage sequentially through a second resonant network and a second full-bridge switching network, and a secondary side of the second transformer network is connected with the load through a second rectifying network. Secondary sides of two transformer units in the first transformer network are in star-type connection with a secondary side of one transformer unit in the second transformer network. This apparatus expands output power and solves voltage-sharing and current-sharing problems.
