<p>A power conversion device comprising: a first diode (D1); a second diode (D2); a first capacitor (C1); a second capacitor (C2); and AC switches (SW1, SW2). The first diode (D1) has a cathode terminal connected to a DC positive bus (11). The second diode (D2) has a cathode terminal connected to the first diode (D1) anode terminal, and an anode terminal connected to a DC negative bus (12). The first capacitor (C1) is connected between the DC positive bus (11) and a neutral point (N1). The second capacitor (C2) is connected between the DC negative bus (12) and the neutral point (N1). The AC switches (SW1, SW2) are connected between the connection point for the first and second diodes (D1, D2), and the neutral point (N1).</p> |
