The embodiment of the invention provides a capacitance box of a maglev train, the maglev train and a voltage stabilization control method. The capacitance box comprises a switch branch, a voltage stabilization branch, a first input end, a second input end, a capacitance box positive electrode output end and a capacitance box negative electrode output end, wherein the switch branch comprises a thyristor and a protection resistor connected in parallel with the thyristor; the voltage stabilization branch comprises a capacitor and a voltage stabilization resistor connected with the capacitor in parallel; the first input end is used for being connected with the positive electrode of an external power supply grid; the second input end is used for being connected with the negative electrode of the power supply grid; and the switch branch and the voltage stabilization branch are sequentially connected between the first input end and the second input end in series; the capacitance box positiveelectrode output end is connected with the series connection part of the switch branch and the voltage stabilization branch; and the capacitance box positive electrode output end is used for being connected with the positive electrode of a bus of the maglev train; and the capacitance box negative electrode output end is connected with the second input end; and the capacitance box negative electrode output end is used for being connected with the negative electrode of the bus of the maglev train. The maglev train comprises the capacitance box. The technical problem that the influence of voltagefluctuation of the power supply network on the train cannot be controlled is solved in the embodiment of the invention.
