Title:
CIRCUIT DEVICE AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208745
Kind Code:
A1
Abstract:
A circuit device (20) is provided with: a core (30) including first core portions (31, 32) and second core portions (33, 34); and a first heat transfer member (40) that is disposed between the first core portions (31, 32) and the second core portions (33, 34). The first heat transfer member (40) is in surface contact with first side surfaces (31s, 32s) of the first core portions (31, 32), and second side surfaces (33s, 34s) of the second core portions (33, 34). The first heat transfer member (40) is thermally connected to a coil (25). Consequently, during a time when the circuit device (20) is operating, a temperature increase of the core (30) can be more uniformly suppressed.
