Patent ID: 7483282

Claim:
In a cyclo-converter that includes a first port having first and second nodes, a second port having first and second nodes, a first switch pair coupled between the first node of the first port and the first node of the second port, a second switch pair coupled between the second node of the first port and the first node of the second port, a third switch pair coupled between the first node of the first port and the second node of the second port, and a fourth switch pair coupled between the second node of the first port and the second node of the second port, each switch pair including a switch of a first topology type and a switch of a second topology type in series connection, a method comprising: switching a first switch of the first topology type to an on state after a magnitude of a current through an output inductor becomes less than a predetermined current threshold; and switching a second switch of the first topology type to an off state a first predetermined time after switching the first switch of the first topology type to the on state.
