Beschreibung
Zusammenfassung:	The full-control rectification circuit comprises a control unit, a resistive device, a first switching device, a second switching device, a third switching device and a fourth switching device, the first end of the resistive device is connected with the positive electrode of a power supply and the first end of the third switching device, the second end of the resistive device is connected with the first end of the first switching device, and the second end of the resistive device is connected with the second end of the fourth switching device. Therefore, the charging and discharging rate of the capacitor is controlled. The control unit is connected with the first switching device, the second switching device, the third switching device and the fourth switching device and used for controlling on-off of all the switching devices according to the working modes of the circuit so as to switch the working modes of the protection circuit, and the protection circuit can achieve the functions of buffering, discharging
