Abstract
An AC charging device for a motor vehicle has a neutral conductor, at least one phase conductor, and at least one rectifier. The neutral conductor and the at least one phase conductor are connected to the rectifier, to which at least one smoothing capacitor is also connected. The AC charging device has a precharge circuit arranged between a mains connection and the at least one smoothing capacitor. The precharge circuit is designed to precharge the at least one smoothing capacitor. The precharge circuit has at least one transistor.
