Abstract
Official abstract text for this publication.
A gate drive circuit includes a first switch and a first capacitor. A first terminal of the first capacitor is electrically coupled to the first switch. The first switch is electrically coupled between the first terminal and a voltage supply of the power transistor. A second terminal of the first capacitor is electrically coupled to the reference potential. The gate drive circuit further includes a first voltage limiter in parallel with the first capacitor. The first voltage limiter limits a voltage across the first capacitor to a first predetermined voltage. The gate drive circuit further includes a second capacitor, a pre-charging circuit arranged between the first terminal of the first capacitor and a first terminal of the second capacitor. The gate drive circuit further includes a third capacitor with a first terminal electrically coupled to a second terminal of the second capacitor and a second terminal electrically coupled to a gate terminal of the power transistor.
