<P>PROBLEM TO BE SOLVED: To reduce the power consumption of cooling fans 6, 8 with a simple structure in an electric power conversion apparatus 1 including an electric power conversion part 3 converting DC output power of solar cells 20 into AC power and the cooling fans 6, 8 cooling the electric power conversion part 3. <P>SOLUTION: An electric power conversion part 3 is housed in a housing 2 and solar cells 20 are disposed on an upper surface of the housing 2. The output of the solar cells 20 is input to the electric power conversion part 3 and the output of the solar cells 20 is supplied to a cooling fan drive device 24 without passing through the electric power conversion part 3. Drive voltages of the cooling fans 6, 8 are obtained according to the power generation amount of the solar cells 20, and drive power of the cooling fans 6, 8 is generated according to the required amounts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
