## Abstract

An inverter device has an inverter stack and a switchboard housing the inverter stack. The inverter stack has an output relay bar connected to an output terminal thereof, and a lower frame configuring a bottom portion and formed from a plurality of frame members connected to form each side of a cuboid. The lower frame is formed such that the frame members configuring one side of a four-sided frame being penetrated by the output relay bar are formed of a non-magnetic body.

## Claims

### Claim 1

An inverter device, comprising:
an inverter stack; and
a switchboard housing the inverter stack,
wherein the inverter stack has an output relay bar connected to an output terminal thereof, and a lower frame configuring a bottom portion and including a plurality of frame members connected to form each side of a cuboid, and
the lower frame is formed such that one of the frame members configuring one side of a four-sided frame being penetrated by the output relay bar is formed of a non-magnetic body.

### Claim 2 (depends on 1)

An inverter device according to claim 1, wherein one of the frame members configuring one side of the frame constructing an upper side of the four-sided frame in the lower frame is formed of a non-magnetic body, and
one of the frame members configuring one side of the frame constructing a lower side of the four-sided frame in the lower frame is formed of a non-magnetic body.

### Claim 3 (depends on 1)

An inverter device according to claim 1, wherein the lower frame includes a front portion comprising one of the frame members configuring one side of the frame constructing an upper side of the four-sided frame in the lower frame, one of the frame members configuring one side of the frame constructing a lower side of the four-sided frame in the lower frame, and longitudinal frame members connecting the one of the frame members in the upper side and one of the frame member in the lower side, and
the frame members forming the front portion are formed of a non-magnetic body.
