Abstract
Systems and methods are described herein for controlling a switch. In some embodiments, circuitry may detect a voltage across the switch. A current reference signal may be generated based on the voltage across the switch. The switch may be controlled based, at least in part, on the current reference signal.
Claims16
An apparatus for controlling a switch, the apparatus comprising:
- a difference signal circuitry configured to detect a voltage across the switch;
- a reference signal circuitry configured to generate a current reference signal based on the voltage across the switch;
- a feedback current circuitry configured to receive a feedback current signal representing a current level in the switch;
- and
- a control circuitry configured to provide a control signal for the switch based, at least in part, on a difference between the current reference signal and the feedback current signal.
2 more elements
A method for controlling a switch, the method comprising:
- detecting a voltage across the switch;
- generating a current reference signal based on the voltage across the switch, the current reference signal being a continuous function of the voltage across the switch;
- receiving a feedback current signal representing a current level in the switch;
- and
- controlling the switch based, at least in part, on a difference between the current reference signal and the feedback current signal.
