In IGBT applications, gate oscillation is one of the most common challenges. It not only affects switching performance but can also trigger overvoltage, overheating, or even device damage.

Firstack possesses over a decade of application experience in optical module-based IGBT driver products, with cumulative shipments exceeding 200,000 units.

Circulating currents during SiC parallel operation

The commonly available board-level driver cores typically integrate four components: Power supply, Isolation(power + signal), Driver, Protection. What remains to be addressed before full deployment?

SiC devices feature faster switching speeds and higher short-circuit currents, posing stringent challenges to the speed and robustness of protection responses. Hope this article provides practical guidance and assistance for validating the short-circuit protection functionality of SiC drivers.

Compared to the IGBT drivers we are all familiar with, what specific differences require our attention when designing drivers for SiC? How can we mitigate risks while fully leveraging its advantages?

Firstack offers a series of standardized IGBT driver solutions, designed to assist PV inverter manufacturers in achieving more efficient, streamlined, and less resource-intensive product development.

3L-ANPC are connected in series with two low-voltage components to increase the DC voltage of the system, which cause an imbalance in the voltage between the inner and outer switches easily in real system, causing the inner switches voltage to exceed half the bus voltage, posing a threat to system operation.
