A method for protecting a controllable semiconductor switch from overload and short-circuiting in a load circuit, the method&#x2014;including detecting an output voltage of the semiconductor switch;&#x2014;comparing a detected output voltage with a predicted switching progress; and&#x2014;deactivating the semiconductor switch if the detected output voltage is lower than the predicted switching progress.

Pulse width modulated controller systems. Implementations may include: a microcontroller coupled with a memory, a switch controller coupled with the microcontroller, and a calibration unit. The calibration unit may include one or more comparators, one or more passive electrical components, and an encoder logic all operatively coupled together and coupled with the microcontroller and with the switch controller where the at least one comparator and the one or more passive electrical components are electrically coupled with a supply voltage to the semiconductor switch and with a load voltage (output voltage) from the semiconductor switch.

Systems and methods for pulse width modulated control of a semiconductor switch

A method is intended to make it possible to drive a PTC electrical load element with a switching unit with the highest possible operational reliability. For this purpose, the electric current is switched off if a predetermined current threshold value is exceeded, the magnitude of the current threshold value being determined from the operating parameters of the load element.
