The utility model discloses a double-path control circuit of a high-frequency frequency converter. The circuit includes two paths of control circuits which are connected with two power supplies respectively. The two paths of control circuits are connected with a frequency converter through a redundancy module. The redundancy module includes two diodes which are connected in parallel. A positive pole of each diode is connected with one path of control circuit respectively. Negative poles of the two diodes are connected with the frequency converter after being connected. Through the redundancy module which is formed through combination of the two diodes connected in parallel, uninterrupted switching of the two paths of the power supplies is realized and no switch device is needed for switching and no UPS emergency power supply is needed in the whole process so that the control process is simple and zero-time switching between the two paths of the control power supplies is realized. Therefore, system stability is increased significantly on the premise that cost is reduced and the circuit is high in usability.
