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.
