Abstract

PURPOSE: The provision of the time detecting process to detect the time in proportion to the flowing angle of the thyristor facilitates to control the opening and closing the gate to cope with the capacitive element by the output of this detecting process, to obtain the counter electromotive force of the motor by the capacitive element, namely the voltage to cope with the rotation.
