The utility model discloses a PID control converter capable of tracking voltage output. The PID control converter comprises a PID control converter body, the PID control converter body comprises a converter body, a heat dissipation block is arranged at the top end of the converter body, a supporting block is arranged at one end of the converter body, a supporting rod is arranged at the top end ofthe supporting block, a cooling fan is arranged at the top end of the supporting rod, and a buffer pad is arranged at the bottom end of the converter body. According to the utility model, the heat conduction pipe is arranged, so that heat in the converter body is conducted out to the heat dissipation block; heat dissipation grooves and heat dissipation holes are formed in the heat dissipation blocks; therefore, the contact area between the heat dissipation block and the air can be increased; therefore, heat dissipation of the PID control converter body is achieved, the working capacity of thePID control converter body is improved, the buffer pad made of the rubber material can effectively reduce vibration of the PID control converter body, and the sound absorption block can effectively reduce noise of the PID control converter body.
