protection threshold value (“Fault detection” in the Fig.1). Despite that a delay td always exists between the fault detection and the time when fault current is under control, the IGBT current is maintained and doesn’t become higher. The IGBT device is usually designed to be able to withstand high shortcircuit current for 10~15 s, which ...

Integrated Switch Current Sensor for Shortcircuit Protection and Current Control of 1.7-kV SiC MOSFET Modules Jun Wang, Zhiyu Shen, Rolando Burgos, Dushan Boroyevich Center for Power Electronics Systems Virginia Polytechnic Institute and State Blacksburg, VA 24061, USA [email protected] Abstract—This paper presents design and implementations of a switch current sensor

The input signal to the optocoupler 6N137 is always low level regardless of whether the control circuit is sent to a high level or a low level to turn off the power tube. Thus, over-current protection is achieved until the circuit is troubleshooted and then restarted. Fig. 4 Strong Driving Circuit of IGBT with Short-Circuit Protection

ues. As a consequence, it is easy to design the protection circuit. Besides, this method requires neither a high-voltage diode for sensing nor a current sensor, so that it is an afford-able method. The protection circuit based on a gate charge characteristic, which monitors the gate–emitter voltage and

To avoid this short circuit condition, Short-circuit Protection Circuit is used. Short-circuit Protection Circuit will divert the flow of current or break the contact between the circuit and the power source. Sometimes we experience power failure with a sudden spark while using some faulty home appliances like oven, iron, etc, then.

II). When a short-circuit occurs, the current supplied by the IGBT increases abnormally with full anode–cathode voltage. In this paper, we present a protection against short-circuit which is integrated with the IGBT structure and based on the simultaneous detection of an anode voltage increase and the gate driving voltage state. 2. Anode ...
