US 2011/0032683 A1 · POWER MODULE AND CIRCUIT BOARD ASSEMBLY THEREOF

Abstract

A power module includes a first bobbin, a primary winding coil, a circuit board assembly and a first magnetic core assembly. The primary winding coil is wound around the first bobbin. The circuit board assembly includes a printed circuit board, a second winding structure, at least one current-sensing element, a rectifier circuit and an electrical connector. The second winding structure has an output terminal. The current-sensing element includes a first conductor. The first conductor is a conductive sheet. A first end of the first conductor is in contact with the output terminal of the second winding structure. A second end of the first conductor is connected to the rectifier circuit. The primary winding coil is aligned with the second winding structure of the circuit board assembly and arranged within the first magnetic core assembly. The primary winding coil and the electrical connector are electrically connected with a system board.
