おそれがあった。Electrolytic capacitor 4 made of copper bars 1 to 3 shown in FIG.
In the connection method, since these copper bars 1 to 3 are narrow conductors, when the number of electrolytic capacitors 4 in parallel or in series is large, the wiring inductance between the PN terminals increases. As a result, due to the increase in wiring inductance, there was a risk that the protection function of the SIRISK element as a switching element would be degraded.
