<p>A power conversion device includes a semiconductor switch series circuit configured by connecting semiconductor switches S p and S n in series; a capacitor series circuit configured by connecting capacitors C dp and C dn in series; a reactor L connected between the series connection point of the semiconductor switches S p and S n and the series connection point of the capacitors C dp and C dn ; and a direct current power source V s connected in parallel to the capacitor C dn or C dp . The semiconductor switch series circuit and capacitor series circuit are connected in parallel, a load Load is connected between the parallel connection points of the two circuits, and the semiconductor switches S p and S n are turned on and off, thereby raising a direct current power source voltage and supplying it to the load Load. By so doing, it is possible to reduce the size and cost of the entire device.</p> |
