Abstract
A power circuit is described that includes a half-bridge and a driver for controlling a first switch of the half-bridge. The driver is configured to cause the first switch to transition between operating in an on-state of the first switch and an off-state of the first switch based at least in part on a driver signal and a voltage at the half-bridge.
Claims20
A power converter comprising:
- a half-bridge that includes a first switch coupled to a second switch at a switching node;
- and
- a driver for controlling the first switch, wherein the driver is coupled to the first switch and configured to cause the first switch to transition between operating in an on-state of the first switch and an off-state of the first switch based at least in part on a driver signal and a voltage at the half-bridge.
A method comprising:
- detecting a voltage at a half-bridge of a power converter, wherein the half-bridge includes a first switch coupled to a second switch at a switching node;
- receiving a driver signal for controlling the first switch and the second switch;
- and
- controlling the first switch of the half-bridge based at least in part on the voltage at the half-bridge and the driver signal, wherein controlling the first switch includes causing the first switch to transition between operating in an on-state of the first switch and an off-state of the first switch.

A power converter comprising:
- means for detecting a voltage at a half-bridge of the power converter, wherein the half-bridge includes a first switch coupled to a second switch at a switching node;
- means for receiving a driver signal for controlling the first switch and the second switch;
- and
- means for controlling the first switch of the half-bridge based at least in part on the voltage at the half-bridge and the driver signal, wherein the means for controlling the first switch includes means for causing the first switch to transition between operating in an on-state of the first switch and an off-state of the first switch.
