Vorrichtung und Verfahren für eine schnelle Fehlererkennung und Übertragung in eine geräteinteraktive unterbrechungsfreie Stromversorgung |
摘要 |
<p>A method and apparatus are disclosed for improving the disturbance pass through characteristics of a line interactive uninterruptible power supply ("UPS"). One disclosed technique uses a naturally commutated fast utility disconnect switch, wherein the switch is self commutated by the UPS inverter forcing the current through the switch to zero. A second disclosed technique uses a gate commutated fast utility disconnect switch and the associated snubber circuits, wherein the fast utility disconnect is opened quickly upon occurrence of a line fault and the energy generated in interrupting the line current is dissipated by the snubber circuits.</p> |
