Abstract
Obtain an electric power converter by which a downsizing and a low cost can be realized in such a way that main components are standardized. A transformer and rectifier elements of a rectifier circuit are configured by using a single module, and a center tap is configured by laminating one pullout portion of a first secondary winding and one pullout portion of a second secondary winding, and a central connecting component is connected to a center tap and a terminal of a smoothing coil which composes a smoothing reactor.
Claims21
An electric power converter comprising:
- an inverter circuit;
- a transformer which is connected to an output side of the inverter circuit;
- a rectifier circuit which is connected to an output side of the transformer, the rectifier circuit comprising rectifier elements;
- a smoothing coil which composes a smoothing reactor which is provided at the output side of the transformer and is connected to an output circuit, which includes the rectifier elements, of the transformer;
- in which a center tap is provided, in the transformer, at a connecting portion of a first secondary winding and a second secondary winding, wherein the first secondary winding and the second secondary winding are a part of a secondary winding;
- and
- an insulative resin, wherein
- the transformer and the rectifier elements are configured as a single module by being within the insulative resin, and
- a pullout portion is configured, at the center tap, by laminating an end portion of the first secondary winding and an end portion of the second secondary winding, and
- the pullout portion of the center tap and the smoothing coil are connected by using a connecting object that extends from the pullout portion, past a lateral side of the insulative resin, and to the smoothing coil.
