SEMICONDUCTOR MODULE

摘要

The present invention relates to a semiconductor module comprising: a power factor correction unit including a main switch unit having a first main switch and a second main switch which perform the switching operations with a certain phase difference, an auxiliary switch unit having a first auxiliary switch and a second auxiliary switch which respectively form delivery routes of existing surplus power before switch-on operation of the first main switch and the second main switch, an inductor unit which is located between an input power end to receive input power and the main switch unit and accumulates or emits energy according to the switching operations of the main switch unit, and an auxiliary inductor unit to adjust an amount of a current supplying to the auxiliary switch unit when the switching operation is performed by the auxiliary switch; an inverter unit; a control unit to control the power factor correction unit and the inverter unit; and a frame unit having the power factor correction unit, the inverter unit and the control unit mounted therein.
