Abstract: Signal converters, systems for power conversion, and methods for adaptive pulse control. The signal converter includes a pulse generator, a level shifter, and a controller. The pulse generator is configured to receive an input control signal for a switch driver. The pulse generator is also configured to generate a set control signal based on the input control signal. The level shifter is configured to generate, based on the set control signal, an output control signal having a first amplitude greater than a second amplitude of the input control signal. The level shifter is also configured to send the output control signal to the switch driver. The controller is configured to detect a common mode transient at a node coupled to the switch driver. The pulse generator is further configured to increase a pulse width of the set control signal when the controller detects the common mode transient.

Abstract: Operating a gate driver. At least one example is a method of operating the gate driver, the method comprising: de-asserting a drive-low terminal of the gate driver; starting a single timer within the gate driver; and after expiration of the single timer asserting a drive-high terminal of the gate driver responsive to assertion of an in-high terminal of the gate driver; and then de-asserting the drive-high terminal; starting the single timer; and after a second expiration of the single timer asserting the drive-low terminal responsive to assertion of an in-low terminal of the gate driver.
