Abstract:
Provided is a power conversion device which can be configured inexpensively and in which initial charging can be performed quickly. Accordingly, the power conversion device (100) is provided with: a power converter cell (10) having a first converter (11) for converting a first AC voltage to a first DC voltage (Vd
c1), a second converter (12) for converting the first DC voltage (Vd
c1) to another voltage (Vd
c2), and a first capacitor (16) charged by the first DC voltage (Vd
c1); and a control circuit (103) for allowing charging of the first capacitor (16) while changing the operational state of the first converter (11) in accordance with the first DC voltage (Vd
c1).
