Title: (EN) SHORT-CIRCUIT PROTECTION METHOD
Abstract: front page image
(EN)

A short-circuit protection method for a circuit having a plurality of power switching elements, includes, when a short-circuit of a first power switching element is detected by detection device that detects a short-circuit of the plurality of power switching elements, performing a cut-off process of cutting off a gate of a second power switching element through which a short-circuit current caused by the short-circuit of the first power switching element flows, and changing a resistance value of a gate resistor of the second power switching element while the cut-off process is performed.
