Inverter with charging capability
First Claim
1. An inverter with charging capability, comprising:
- an arm circuit in whichan upper arm switching element to which a positive electrode of a battery is connected anda lower arm switching element to which a negative electrode of the battery is connectedare connected;
a first capacitor having one end connected to the positive electrode;
a second capacitor connected between the other end of the first capacitor and the negative electrode;
a first diode having a cathode electrode connected to a connection point between the upper arm and lower arm switching elements; and
a second diode having a cathode electrode connected to the other end of the first capacitor,wherein an anode electrode of the first diode and an anode electrode of the second diode are directly connected at a feeding point, and power is directly supplied from an external power supply to the feeding point.

Abstract
An inverter includes an arm circuit, a first capacitor, a second capacitor, a first diode, and a second diode. In the arm circuit, upper arm switching elements to which a positive electrode of a battery is connected and lower arm switching elements to which a negative electrode of the battery is connected are connected. The first capacitor has one end connected to the positive electrode of the battery. The second capacitor is connected between another end of the first capacitor and the negative electrode of the battery. The first diode has a cathode electrode connected to the connection point between the upper arm and lower arm switching elements. The second diode has a cathode electrode connected to another end of the first capacitor. Power is supplied from an external power supply to an anode electrode of the first diode and an anode electrode of the second diode.
