Abstract

PURPOSE:To prevent engine-stop (hereinafter simply en-st) by providing a control circuit for outputting a gate pulse in a thyristor gate circuit interposed in a power line of a generator to gradually increase the average voltage when a motor load circuit is started. CONSTITUTION:When an operating switch 5 is turned on to start the starting of a motor 7, a gate pulse from a control circuit 9 is output to a thyristor gate circuit 8 in such a manner that a designated time is delayed from the zero cross point of a generator output and the delay time tx is gradually decreased within the range of less than half the period of the generator output, whereby when the motor load circuit 4 is started, the average voltage of current supplied to the motor load circuit 4 is gradually increased. Accordingly, the motor 7 is slowly started without a rush current to prevent overload of an engine due to rush current and the occurrence of en-st caused thereby.
