PROBLEM TO BE SOLVED: To obtain a power conversion device capable of step-up operation with a reduced noise, in a circuit of an interleave configuration including a plurality of step-up chopper circuits disposed in parallel.SOLUTION: Each step-up chopper circuit includes: a first reactor 301; a first diode 302 having an anode connected to the first reactor 301; a first bus having the first reactor 301 and the first diode 302 connected thereto; a second bus having a second reactor 303 connected thereto; and a semiconductor switch element 305a connected between the anode of the first diode 302 and the second bus. A plurality of such step-up chopper circuits are connected in parallel.SELECTED DRAWING: Figure 3 |
