Characteristics
A laminate bus bar is a board that restrains an abnormal voltage in a power circuit using power semiconductor elements such as IGBT and IPM at the time of high-speed switching, to improve characteristics when performing high-speed operations. We have achieved the following by laminating an insulation film sheet with a metal conductor.
- High-speed switching with reduction of inductance between conductors
- Rationalization of wiring and reduction of assembly time with reduction of the number of parts
- Reduction of the assembly space
- High reliability of electrical connection parts
- High partial discharge inception voltage level
In addition, a lightweight laminate bus bar with an aluminum conductor has been put to practical use to replace the general copper conductor.
Product name
