Abstract

PURPOSE:To reduce the time in which the processing device is related to the calculation of the ignition time for the subject driving device by a method wherein the ignition time is calculated in synchronization with the power source, the time required for the calculation is subtracted from the calculated value and an ignition pulse is generated after the lapse of the remaining time. CONSTITUTION:In the circuit with which the DC motor 111 is controlled by a thyristor three-phase inverted parallel inverter 114, the signal sent from a synchronous pulse generating circuit 120a is inputted to a digital control section 122 and a reference timer 201 is synchronization with a three-phase power source. At the digital control section 122, an armature current Ia and a current application command LCM, an ignition time Ts in accordance with the performance mode is calculated, and at the same time, the calculation finished time is counted using the timer 201. Then, after the calculation has been finished, the Te is subtracted from the Ts, and the remaining time Tr is inputted to the counter of the ignition pulse generating circuit 123a, thereby enabling to generate the ignition pulse after the remaining time Tr has elapsed.
