Title:
CURRENT DETECTION DEVICE AND POWER CONVERSION DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/199626
Kind Code:
A1
Abstract:
Provided is a current detection device having a smaller size and a higher density, or a power conversion device equipped with the current detection device.
This current detection device or power conversion device is provided with a plurality of conductive bodies that correspond to currents of a plurality of phases, and a current sensor. The conductive bodies are formed such that the conductive bodies respectively have conductive body portions wherein the currents flowing in the conductive bodies are substantially parallel to each other, and in a cross-section in the perpendicular direction with respect to the direction of the currents flowing in the conductive body portions, the current sensor is disposed within a region among the conductive body portions, and on the basis of synthesis of magnetic field vectors generated due to the currents, the current sensor outputs information of the currents flowing in the conductive bodies.
