Abstract
A driver for improving reliability of a switch in a power device, comprising one or more sensors configured to sense an operational parameter of a power device. The driver comprises a controller configured to receive one or more sensor values from the respective sensors. The controller is configured to adjust a driving pulse according to the sensor values. The controller is configured to apply the driving pulse to one or more control terminal of one or more switch of the power device.
Claims20
An apparatus, comprising:
- a switch circuit comprising a first terminal, a second terminal, and a control terminal;
- a sensor configured to measure a voltage magnitude between the first terminal and the second terminal;
- and
- a switch driver circuit configured to:
- receive a pulse width modulation (PWM) signal from a controller;
- receive the voltage magnitude from the sensor;
- determine a current magnitude based on the voltage magnitude;
- and
- apply a driving pulse comprising the current magnitude to the control terminal according to the PWM signal.
