Abstract:
A control substrate capable of effectively reducing noise input to a plurality of MOSFETs is provided. The control substrate includes at least three parallel snubber circuits (132, 134, and 135). Each of the parallel snubber circuits (132, 133, and 134) is connected in parallel with each of U-phase MOSFETs (126a and 126b), V-phase MOSFETs (127a and 127b), and W-phase MOSFETs (128a and 128b).
