Abstract
A method for operating a gate driver system includes measuring a first parameter according to a first priority schedule synchronously to a first edge of a switching signal generated by a gate driver integrated circuit and having a variable duty cycle. The method includes after measuring the first parameter of the gate driver system and prior to a second edge of the switching signal, measuring at least a second parameter of the gate driver system according to a first round-robin schedule synchronously to the first edge of the switching signal.

A method for managing measurements in a gate driver system, the method comprising:
- measuring a first parameter according to a first priority schedule synchronously to a first edge of a switching signal generated by a gate driver integrated circuit and having a variable duty cycle;
- and
- after measuring the first parameter of the gate driver system and prior to a second edge of the switching signal, measuring at least a second parameter of the gate driver system according to a first round-robin schedule synchronously to the first edge of the switching signal.
A gate driver system comprising:
- a driver circuit of an integrated circuit;
- and
- a controller circuit of the integrated circuit configured to cause the integrated circuit to measure a first parameter according to a first priority schedule synchronously to a first edge of a switching signal generated by the driver circuit and having a variable duty cycle, and after measuring the first parameter and prior to a second edge of the switching signal, to measure at least a second parameter according to a first round-robin schedule synchronously to the first edge of the switching signal.
A method for managing measurements in a control system, the method comprising:
- measuring a current through a high-power drive device and a voltage across the high-power drive device according to a first priority schedule synchronously to a first edge of a switching signal having a variable duty cycle;
- and
- after measuring the current and the voltage and prior to a next edge of the switching signal, measuring additional parameters according to a first round-robin schedule synchronously to the first edge of the switching signal.
