SWITCH SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240259018 titled 'SWITCH SYSTEM
Simplified Explanation
In a switch system, a voltage clamping element is connected in parallel to a semiconductor switch. An active clamping circuit is connected between the control terminal and a main terminal of the switch, consisting of diodes and a control switch. The control unit manages the control switch, ensuring the first diode's breakdown voltage is lower than the clamp voltage of the clamping element.
