Abstract
A power converter is described which is comprised of a filter circuit component including a reactor and capacitor wherein the reactor includes a core which consists of a magnetic substance which is disposed around a conductive wiring member, a noise generating component which radiates noise wherein the noise generating components are disposed adjacently to the filter circuit component and a shielding plate which shields out the radiating noise. The shielding plate is disposed between the filter circuit component and the noise generating component. The conductive wiring member and the shielding plate are composed as one body electrically insulated from each other.
Claims22
A power converter comprising;
- a filter circuit component including a reactor and capacitor, wherein the reactor includes a conductive wiring member which acts as a coil and a core composed of a magnetic substance which is disposed around and covers the conductive wiring member;
- a circuit provided with a noise generating component which radiates noise when the noise generating component is made active, wherein the noise generating component is positioned adjacently to the filter circuit component, the generated noise including at least magnetic noise or electrostatic noise;
- and a shielding plate which shields the noise radiated from the noise generating component, wherein the shielding plate is formed to have a plate surface, is built between the filter circuit component and the circuit provided with the noise generating component such that the plate surface is opposed to the circuit provided with the noise generating component, and is earthed;
- wherein both of the conductive wiring member and the shielding plate are formed as a one body in which both of the conductive wiring member and the shielding plate are electrically insulated from each other.
