Active Avalanche Protection for Fly Back Converter |
| 摘要 |
The present document relates to power converters. In particular, the present document relates to the protection of the power switches of power converters. A controller configured to control a switched-mode power converter is described. The controller comprises a control pin for controlling a state of a power switch of the switched-mode power converter using a control signal; and a sensing pin for receiving a sensed current signal indicative of a current through the power switch. The controller is configured to detect a break-through situation of the power switch based on the state of the power switch and based on the sensed current signal. |

1. A controller configured to control a switched-mode power converter, comprising:
a control pin for controlling the state of a power switch of the switched-mode power converter using a control signal; and a sensing pin for receiving a sensed current signal, wherein the sensed current signal is indicative of a current through the power switch and wherein the controller is configured to detect a break-through situation based on the state of the power switch and the sensed current signal. |
