VOLTAGE CONTROL FOR AN OUTPUT TRANSISTOR OF A SIGNAL OUTPUT STAGE |
摘要 |
<p>The invention relates to a signal (feed) separator for dead-zero or live-zero measurement signals. The signal (feed) separator has a primary-side (feed) input, a secondary-side output, a direct-current transformer for transferring primary-side measurement input current, an output stage for providing a secondary-side measurement output current, and an auxiliary energy feed-in for supplying the primary side and for supplying the secondary side. The auxiliary voltage of the auxiliary energy feed-in is controlled on the secondary side by a control device with the aid of a measuring device in such a way that the power loss of the output stage is substantially independent of a load connected in the operating state.</p> |
