Abstract
A system includes a power converter, wherein the power converter includes: a switch; and one or more controllers configured to control an operation of the switch; wherein the one or more controllers include: a first feedback loop configured to detect a change in voltage of the switch; a second feedback loop configured to detect a change in current of the switch; and a switch driver configured to generate a control signal for the switch, based on the change in voltage detected by the first feedback loop and the change in current detected by the second feedback loop.
Claims20
A system comprising a power converter, wherein the power converter includes:
- a switch;
- and
- one or more controllers configured to control an operation of the switch;
- wherein the one or more controllers include:
- a first feedback loop configured to detect a change in voltage of the switch, wherein the first feedback loop includes a first transconductor configured to output a first current signal based on the change in voltage detected by the first feedback loop;
- a second feedback loop configured to detect a change in current of the switch, wherein the second feedback loop includes a second transconductor configured to output a second current signal based on the change in current detected by the second feedback loop;
- and
- a switch driver configured to generate a control signal for the switch, wherein the control signal includes a combination of the first current signal and the second current signal.
A system comprising one or more controllers, the one or more controllers including:
- a first feedback loop configured to detect a change in voltage of a switch, wherein the first feedback loop includes a first transconductor configured to output a first current signal based on the change in voltage detected by the first feedback loop;
- a second feedback loop configured to detect a change in current of the switch, wherein the second feedback loop includes a second transconductor configured to output a second current signal based on the change in current detected by the second feedback loop;
- and
- a switch driver configured to generate a control signal for the switch, wherein the control signal includes a combination of the first current signal and the second current signal.
A method comprising:
- generating, by a first transconductor of a first feedback loop, a first current signal based on a change in voltage of a switch;
- generating, by a second transconductor of a second feedback loop, a second current signal based on a change in current of the switch;
- and
- generating a control signal for the switch, wherein the control signal includes a combination of the first current signal and the second current signal.
