for trucks. The demonstrator consists of eight low ohmic MOSFETs connected in parallel and mounted on a structured copper IMS (insulated metal substrate) board together with a gate driver circuit (AUIR3242S) to switch those MOSFETs on and off and protection measures against overvoltage and ...
Over-current protection scheme for SiC power MOSFET DC circuit breaker A material in which conductive powder is mixed with resin is filled in the grooves 10 to form a resistor 13 for a protecting circuit. Then, a power transistor having an overcurrent protecting function to indicate an equivalen...
2021 年 1 月 to reduce the risk of overcurrent. By setting up a short-circuit test platform, it is verified that when a short-circuit fault occurs in the three-level circuit, the flying capacitor with large capacitance can protect SiC MOSFET from overvoltage, and the short-circuit prot...
is necessary to carry out overvoltage protection and overcurrent protection. According to the overvoltage caused by short circuit, combined with the short circuit protection method, this paper proposes a method of adding a flying capacitor with a large capacitance to the Neutral Point Clamped (...
The amount of instantaneous short-circuit current that can be provided is the first thing to consider when selecting/designing the MOS transistor driver; the second thing to consider is that the NMOS, which is commonly used for high-end driving, requires the gate voltage to be greater than ...
