Title:
INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/204044
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an inverter device having improved current detection precision by suppressing the variation in the distribution of current flowing though a shunt resistor without using a separate member. In a printed circuit board (40) of this inverter device (20), a first conductive pattern part (51) connected to a shunt resistor (31) includes: a first central region (510); a first rightward protruding region (511) protruding to the right from the first central region (510); and a first leftward protruding region (512) protruding to the left from the first central region (510). The ratio SA2/SA1 of the area SA2 of the first leftward protruding region (512) to the area SA1 of the first rightward protruding region (511) is set within a range of 0.6-1.6, and thus the variation in the distribution of the current flowing through the shunt resistor (31) can be suppressed.
