Crosstalk occurs when the fast switching of an active device induces disturbances in the complementary device, a phenomenon common in voltage source converter (VSC) phase legs. In solid-state circuit breakers (SSCBs) with transient voltage suppression (TVS) diodes, it can still arise without a traditional phase-leg structure, as high dv/dt transients from the TVS diode couple into the gate loop, causing gate voltage undershoot. This paper analyzes the crosstalk mechanisms in SSCBs with TVS diodes by identifying parasitic coupling paths, reviews mitigation strategies from both VSC and SSCB contexts, and validates their effectiveness experimentally, providing guidance for improving high-speed SSCB robustness and reliability.
