<p>PURPOSE:To feed the detection signal of an exciter to other device by flowing an exciting current during the prescribed period after opening the exciter circuit. CONSTITUTION:The second flywheel circuit 6 having an impedance of several times of the impedance in the forward direction of the first flywheel circuit 5 at an automatic voltage regulator 2 side is connected in parallel with an exciting coil 1. When this circuit is used, a flywheel current flows to the first circuit 5 in case of normal control that the exciter is closed, and a flywheel current due to the induced voltage of the exciting coil flows through the second circuit for the prescribed time when the exciter is opened. Thus, the flywheel current can be held for the prescribed time even after the exciter is opened, thereby outputting the output voltage of a generator 3 for the prescribed time.</p> |
