PROBLEM TO BE SOLVED: To provide a small-sized and light weight power supply which enables the system interconnection using a DC power supply. SOLUTION: This power supply comprises a first reactor 3c including a first winding and a second winding which are magnetically coupled, a first capacitor 5, and a second capacitor 6. A primary side is formed of the first winding 3a of the first reactor 3c, first diode 4, and a semiconductor switch 2 for charging the first capacitor, and a secondary side is formed of the secondary winding 3b of the first reactor 3c, second diode 7, third diode 8 and second reactor 9 for charging the second capacitor 6. |
