Abstract

PURPOSE:To achieve operation control without causing overshooting in the control volume from the start by changing the upper and the lower limits of PI (Proportion/ integration) at each sampling cycle with a PI limit pattern during a fixed period from the start. CONSTITUTION:A digital phase detector 2 outputs a signal DPH synchronizing the cycle of a 3 phase AC voltage signals er, es and et from a power converter 1. On the other hand, a computer 3 performs a soft processing adding a limit pattern fetch between points (a) and (b) using a control reference REF of a digital level and a feed back signal (f) from the power converter 1. This PI operation provides a digital phase reference signal Ee to determine the output timing for a firing pulse TP from a gate logic circuit 4. Thus, the feed back level becomes zero at the start, enabling the operation control without over shuting in the control level from the start when PI value increases extremely.
