<P>PROBLEM TO BE SOLVED: To realize an inexpensive electric power conversion apparatus. <P>SOLUTION: An electric power conversion apparatus includes: multiple power semiconductor devices U to Z; a gate driving circuit 4 driving the multiple power semiconductor devices U to Z; radio transmission means 7 for transmitting a gate signal to the gate driving circuit 4; a signal cable connecting with the radio transmission means 7 and to which the gate signal is input; and a housing 17 housing the multiple power semiconductor devices U to Z, the gate driving circuit 4, and the radio transmission means 7. The housing 17 has characteristics which shield a signal used for communication in at least the radio transmission means 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
