The utility model belongs to the technical field of converters, and particularly relates to a three-level converter which comprises an equipment box. A three-level converter body is arranged in the middle of the equipment box; a heat dissipation plate is fixedly connected to the bottom of the equipment box; a positioning rod is fixedly connected to the middle part of the equipment box; a plurality of groups of positioning rods are arranged in the middle of the equipment box; motors are fixedly connected to the end parts of the multiple groups of positioning rods; the middle part of the motor is rotationally connected with fan blades; a supporting rod is fixedly connected to the middle of the heat dissipation plate. According to the steps, when the three-level converter body works, gas in the equipment box can be exchanged with the outside, so that more heat accumulated in the equipment box can be reduced, and the three-level converter body can be cooled when working; the situation that the three-level convert
