Abstract: PROBLEM TO BE SOLVED: To provide a two-wire soft start circuit with a triac inserted into only two of three lines wherein production of unbalanced currents between phases is prevented and thus stable start is possible. SOLUTION: The soft start circuit is inserted between the phases R, S, and T of a three-phase power supply and a motor 11 supplied with power from the phases R, S, and T of the power supply. Triacs TR1 and TR2 are inserted into two of the three phases. The soft start circuit is provided with an arithmetic unit 16 that controls gate trigger signals so that the angle of ignition will differ between the triacs TR1 and TR2 of the two phases. Thus the unbalanced current in the motor 11 is reduced and further the motor 11 is gently started.
