Patent ID: 7015658

Claim:
A driving circuit configured in a three-phase inverter, comprising: a first switch assembly including a first high-side switch connected between an input voltage and a first node, and a first low-side switch connected between said first node and a reference voltage; a second switch assembly including a second high-side switch connected between said input voltage and a second node, and a second low-side switch connected between said second node and said reference voltage; a third switch assembly including a third high-side switch connected between said input voltage and a third node, and a third low-side switch connected between said third node and said reference voltage; and a three-phase transformer having a primary side with three terminals connected with said first, second and third nodes, respectively, and a secondary side with three terminals connected with a first, second and third loadings, respectively; wherein said switches are switched for generating a first AC voltage between said first and second nodes, a second AC voltage between said second and third nodes, and a third AC voltage between said third and first nodes, respectively, so as to be transformed by said three-phase transformer to generate a first AC current for said first loading, a second AC current for said second loading, and a third AC current for said third loading, respectively.
