Claim Text:
1. A start control circuit, comprising a first switch unit, a start control unit and a second switch unit; an output port of the first switch unit is connected to an input port of the start control unit, an output port of the start control unit is connected to an input port of the second switch unit; the first switch unit is configured to determine a charging path of the start control unit according to input signals of different start modes; the start control unit is configured to carry out the corresponding start modes, and store start energy of the corresponding start modes during a period of charging time corresponding to the charging path, thereby control a current of the second switch unit at a starting moment; the period of charging time is soft start time; the second switch unit is configured to control an external circuit by receiving gating signals outputted from the start control unit; the start modes include a two-dimension start mode and a three-dimension start mode, the charging path includes a first charging path and a second charging path.
