Abstract

A power conversion apparatus connected to three or more voltage units, includes three or more power conversion circuits connected to respective units of the three or more voltage units; and a multiport transformer connected to the three or more power conversion circuits at mutually different ports, in which at least one voltage unit of the three or more voltage units is an electrical load.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A power conversion apparatus connected to three or more voltage units, the power conversion apparatus comprising:
 three or more power conversion circuits connected to respective units of the three or more voltage units; and   a multiport transformer connected to the three or more power conversion circuits at mutually different ports, wherein   the three or more power conversion circuits and the multiport transformer are configured as a multiple active bridge in which each of the three or more power conversion circuits is a switching circuit configured as a bridge circuit,   the three or more voltage units include at least a high voltage battery, a storage battery and an electrical load.   
     
     
         2 . The power conversion apparatus according to  claim 1 , wherein each switching circuit, of three or more switching circuits, is a full bridge circuit. 
     
     
         3 . The power conversion apparatus according to  claim 1 , wherein each switching circuit, of three or more switching circuits, is a half bridge circuit. 
     
     
         4 . The power conversion apparatus according to  claim 1 , wherein
 at least one switching circuit, of three or more switching circuits, is a full bridge circuit, and   at least one other switching circuit, of the three or more switching circuits, is a half bridge circuit.
