Power unit

Abstract

A power unit includes: a transformer including a first winding and a second winding, the first winding being connected to a first voltage part, and the second winding being connected to a second voltage part, a voltage potential of the first voltage part being higher than the voltage potential of the second voltage part; and a first housing including an inner shielding layer, an insulating layer, and an outer shielding layer arranged sequentially from inside to outside, the insulating layer fully covering the first voltage part and the first winding, the inner shielding layer being at the same voltage potential as the first voltage part, and the outer shielding layer being grounded.
