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?

By the end of June 2025, the cumulative newly installed Photovoltaics (PV) grid-connected capacity in the first half of the year had reached 211.61 GW. Among this, distributed PV installations account...

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.
