<p>Capacitors (C1, C2) which are connected in series to each other are connected to both ends of a DC power supply (1), respectively. One end of a power system (2) and one end of a reactor (L) are connected to the respective nodes of the capacitors (C1, C2). A capacitor (C3) is connected to both ends of the power system (2). One end of a first switch unit (S1, D1) is connected to the positive polarity side of the DC power supply (1) and the other end of the first switch unit is connected to the other end of the reactor (L). One end of a second switch unit (S2, D2) is connected to the negative polarity side of the DC power supply (1) and the other end of the second switch unit is connected to the other end of the reactor (L). One end of a third switch unit (S3, D3) is connected to the other end of the reactor (L) and the other end of the third switch unit is connected to the other end of the power system (2). One end of a fourth switch unit (S4, D4) is connected to the other end of the reactor (L) and the other end of the fourth switch unit is connected to the other end of the power system (2).</p> |
