If you are designing gate driver for SiC devices, we know what you are going through. The problem with the usual mainstream SiC gate drives is that the circuit layout and routing is not optimised which acts as an antenna. The parasitic inductance of the gate loop is such that it resonates with parasitic gate capacitance. It has slow short circuit detection time which is > 3uSec along with being very sensitive to EMI causing false short circuit detection and disrupting operation. 

It took us years to perfect the art of SiC gate drivers where we have been able to eliminate all the above defined problems, creating a low cost, compact, fast reacting and immune SiC gate driver with very fast short circuit detection 2-3usec and protection.

In any application when a cold start or black start is needed i.e. when the battery of a power supply is completely flat and only high voltage is available, this circuit can charge the battery of the power supply and start the system by using the high voltage.

In some applications where only high voltage is present and power is needed for the controller , transducers and gate drives, our power supply can step down the high voltage into an isolated and regulated low voltage. The output power range is from some watts to 100 watts. and the input voltage range is some hundred of volts to few kV and the output voltage ranging from 5V to 24V

A unique gate driver which gives user an ability to control the turn on and turn off behaviour or in other words dv/dt and di/dt of the IGBT, MOSFET and JFET and GaN based HEMT are controllable by modulating gate current in real time. The design is very flexible to be physically modified to accommodate various package sizes including open source IGBT module packages.

We have designed a self powered high voltage detector which can indicate the presence of high voltage. Its operating range is from 0V to 5kV. It has two ways to indicate the presence of voltage i.e. by an LED and by fibre optic. It can also be modified to send a high voltage presence signal over WiFi  or LoRa communication protocol.

Currently developing a PCB based high speed, modular EV charger. Each module is capable of an output power of 75kW and the idea is to put two of them in parallel to achieve 150kW for high speed charging.
