摘要 |
<p>The installation has an alternating/direct voltage converter comprising a rectifier (REC) and a capacitor (CM) between input terminals of a direct current motor (MOT) mechanically connected to a door (GD) of a building or a gate. The capacitor is charged by a rectified alternating voltage (V1) through a switch (TR) controlled by a control circuit (3) at a frequency of the rectified voltage. An independent claim is also included for an installation supply control method.</p> |
