Problems solved by technology

[0008] In this method, while the AC current side (hereinafter, the first side) and the DC current side (hereinafter, the second side) are insulated from each other, by using a separate insulating element (for example, an integrated circuit (IC) using a semiconductor ) etc.) It is inconvenient to insulate the first side and the second side from each other, and as a result, in the converter in the prior art, there is a problem that the size of the converter is increased enough to accommodate the insulating element
