Abstract
An inverter power module for use in an electric/electronic device includes a driving circuit board, a power transformer mounted on the driving circuit board, an inverter transformer mounted on the driving circuit board, and a blocking unit to block a magnetic flux that is generated from the inverter transformer from being emitted to the outside. With this, the magnetic flux that is generated from the inverter transformer is blocked from being emitted to the outside, thereby allowing an EMI noise, a heating problem, a noise of the system circuit, etc. to be minimized.
Claims8
An inverter power module for use in an electric/electronic device, comprising:
- a driving circuit board;
- a power transformer mounted on the driving circuit board;
- an inverter transformer mounted on a first side of the driving circuit board, comprising a cover;
- and a blocking unit which blocks a magnetic flux that is generated from the inverter transformer from being emitted to the outside;
- wherein the blocking unit comprises a first blocking unit having a second core, and
- wherein the cover comprises an inserting groove formed therein into which the second core is detachably disposed such that the cover surrounds a top surface and a bottom surface of the second core entirely when the second core is disposed in the cover.
