  • Patent number: 7173834
    Abstract: A half-controlled silicon control rectifying system and method thereof are provided. In this case, the first detection unit detects the zero cross phase of the triphase AC in input port thereof. The second detection unit detects the voltage of the DC bus. Then the control unit controls the silicon-controlled rectifying unit by software. Therefore, the efficiency of soft actuation is achieved.
