The invention discloses a hybrid four-level rectifier, which mainly comprises an A-phase circuit, a B-phase circuit, a C-phase circuit, a capacitor C1, a capacitor C2, a capacitor C3 and a resistor R,wherein two ends of the capacitor C1 are recorded as a g end and an h end separately; two ends of the capacitor C2 are recorded as an h end and a j end separately; two ends of the capacitor C3 are recorded as a j end and a k end separately; the A-phase circuit, the B-phase circuit and the C-phase circuit are connected in parallel and then connected to the g end; the capacitor C1 is connected withthe capacitor C2 through the h ends in series; the capacitor C2 is connected with the capacitor C3 through the j ends in series; and the k end of the capacitor C3 is connected with the resistor R inseries and then connected to the g end. According to the hybrid four-level rectifier, the number of output levels is increased, reduction of voltage stress of a switching device is facilitated and theswitching device is applicable to medium-voltage high-power occasions. According to the hybrid four-level rectifier, the harmonic distortion rate of input current is also reduced, the switching lossof a converter is reduced, the switching frequency of the converter is improved, the volume of a passive device is reduced and the power density of the converter can be improved. The hybrid four-levelrectifier is applicable to medium-voltage high-power application occasions and low-voltage high-power density application occasions.
