Patent ID: 7468897

Claim:
A power converter for stepping down and converting AC voltage to DC voltage, said power converter comprising: first and second input connections for inputting output of said AC voltage; a first capacitor and a second capacitor interposed in series on a first electric connection line between said first input connection and said second input connection, in order from a side of said first input connection; a first diode interposed between the first capacitor and said second capacitor on said first electric connection line so that its forward direction is toward said second input connection; a second diode interposed on a second electric connection line so that its reverse direction is toward said second input connection, said second electric connection line connecting a point between said first capacitor and said first diode on said first electric connection line, and said second input connection; a first output connection for output of said DC voltage, which is connected between said first diode and said second capacitor on said first electric connection line; and a second output connection for output of said DC voltage, which is connected to said second input connection, and a third capacitor, one end of which is connected between said first capacitor and said first diode on said first electric connection line, and the other end of which is connected to said second input connection.
