Abstract: An inverter circuit may include an inverter, a driver coupled to the inverter, and a slew rate control module configured to modify a slew rate of the driver. The slew rate may be modified based on a magnitude of a load driven by the inverter circuit. The magnitude of the load driven by the inverter circuit may be indicated by a current representing a load current or a voltage representing an input voltage. The slew rate may also be modified based on a mode configuration of the inverter circuit.

Abstract: According to at least one aspect, a circuit for controlling a power converter including an inductor having a terminal coupled to a supply voltage by a switch is provided. The circuit includes a detector configured to detect voltage transient events in an output voltage of the power converter and generate a control signal based on the detected voltage transient events and a control signal generator configured to receive the control signal and control operation of the switch based on the control signal at least in part by varying an on-time of the switch during the voltage transient events and holding the on-time of the switch constant when no transient event is detected by the detector.
