Abstract
PURPOSE:To perform speed feedback without a speed detection element, by providing a current positive feedback circuit, which has the feedback rate dependent upon the product between the impedance independent of dynamic movement of the conversion apparatus and the feedback coefficient, and a voltage negative feedback circuit having the feedback rate of the feedback coefficient. CONSTITUTION:For the purpose of equalizing the system, which drives conversion apparatus 2 by overall four-terminal circuit network 7 subjected to composite feedback of voltage feedback and current feedback, and the system which performs speed feedback separately by using a speed detection element, feedback rate betai of betai circuit 6 of the current positive feedback circuit is determined by the product between the feedback coefficient indicated by beta/xsi12 and impedance xsi11 independent of dynamic movement of conversion apparatus 2, and feedback rate betae of betae circuit 4 of the voltage negative feedback circuit is caused to be equal to the feedback coefficient of current positive feedback. Consequently, speed feedback is performed without a speed detection element.
