The VVVF used on this train sounds like that of the CT251 trains used on the Thomson East-Coast Line of Singapore MRT.

@@airrailtravel Actually CT251 uses Mitsubishi hybrid SiC-IGBT-VVVF (model no.: MAP-124-75V298) with 120kW 3-phase AC induction motors (model no.: MB-5162-A). C371 is much older so it uses IGBT-VVVF inverter MAP-184-75VD139 with 175kW induction motors (model no.: MB-5113-A), while C381 uses MAP-184-75VD139A with IM model MB-5113-A2.
