LOCKOUT SWITCHING STRATEGY FOR PREVENTING HIGH VOLTAGE TRANSITION |
摘要 |
<p>A protection circuit includes a first switch, a second switch and a third switch. The first switch, the second switch and the third switch are configured to generate lock signals indicative of an electrical voltage transition on the respective phases of a multi-phase power signal. A control circuit is configured to prevent the first switch from changing state if the second switch or third switch is changing state.</p> |
