Design and fabrication of new high voltage current limiting devices for serial protection applications

SiC power semiconductor devices for new applications in power electronics

“…All these constraints will globally define the electrical specifications of this kind of device. Up to now, only few semiconductor current limiter structures have been described in the literature [17], [16]. Although Current Regulative Diode components already exist, their voltage and current capabilities (V BR = 100V , I MAX = 10mA), do not allow to use them in power systems.…”

SiC Current Limiting FETs (CLFs) for DC Applications

“…Such a feature is also required in more electric aircraft (MOA) applications. To address this point, various semi-conductors based solutions have been presented in the past, from low current ratings [2] to high current ratings [3], being either monolithic [4] or hybrid solid state circuit breaker [5] solutions. For PV applications, bypass diodes are commonly used to protect strings against faults, and/or to keep a generation plant operational in case of shading.…”

Electrical and electrothermal 2D simulations of a 4H-SiC high voltage current limiting device for serial protection applications

“…For comparison with the silicon case, we studied a similar structure, as there is no commercial silicon current limiting device acting in the range of 20A/600V. The silicon device is a power MOSFET with an implanted channel [13], the low doped region is optimized for 600V (45 µm/10 14 cm -3 ).…”
