Capacitor reverse connection protection device, capacitor equipment and capacitor reverse connection protection method thereof

Abstract

The invention discloses a capacitor reverse connection protection device, capacitor equipment and a capacitor reverse connection protection method thereof. The device comprises a drainage unit, the drainage unit is used for draining the leakage current generated by reverse connection of the capacitor to a set safety position under the condition that the capacitor generates the leakage current dueto reverse connection of the polarity. According to the scheme provided by the invention, the problem of poor use safety caused by explosion when the polar capacitor is reversely connected can be solved, and the effect of improving the use safety of the polar capacitor is achieved.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a reverse capacitance protection device, a capacitor device and a reverse capacitance protection method thereof, in particular to a reverse capacitance protection circuit, a capacitance device with the reverse capacitance protection circuit, and The capacitive reverse connection protection method of the capacitive device; wherein, the capacitive device is, for example, a power unit or a power supply unit. Background technique [0002] In the electronics industry, capacitors can be said to be indispensable. However, some of the capacitors are non-polar, and it doesn't matter if they are connected positively or negatively. And some capacitors such as electrolytic capacitors do have polarity, that is to say, this kind of capacitor can only be connected positively, not reversely; if reversely connected, due to the internal structure of the capacitor itself, its...
