Patent ID: 8288887

Claim:
An electrical system for use in a vehicle comprising: an alternating current (AC) interface; a first conversion module coupled to the AC interface; an inductive element coupled between the AC interface and the first conversion module; and a control module coupled to the first conversion module, wherein the control module is configured to: operate the first conversion module in a bidirectional operating mode to deliver current to the AC interface in a first direction, wherein the first conversion module commutates a current through the inductive element bidirectionally in the bidirectional operating mode; obtain the current through the inductive element; and when a magnitude of the current through the inductive element in the first direction is greater than a first threshold value, operate the conversion module in a unidirectional operating mode to deliver current to the AC interface in the first direction, wherein the first conversion module commutates the current through the inductive element unidirectionally in the first direction in the unidirectional operating mode.
