The invention discloses a switchable energy feedback electromagnetic suspension and a control method. The switchable energy feedback electromagnetic suspension comprises a sensor, a central control unit (ECU), an electromagnetic vibration reduction unit, a three-phase rectifier, a two-stage DCDC converter, an energy feedback circuit and an energy consumption circuit body. The suspension comprises an energy feedback mode and an energy consumption mode which can be switched, in the energy feedback mode, energy generated by vibration is absorbed through a super capacitor, and the vibration reduction performance of the suspension is guaranteed while the energy is recycled; and in the energy consumption mode, energy generated by vibration is dissipated through heating of the resistor, the excellent vibration reduction performance is guaranteed, meanwhile, secondary storage is conducted on the super capacitor, and the energy feedback efficiency is improved. According to the suspension system and the control method, the energy feedback efficiency can be effectively improved on the premise that the vibration reduction performance is guaranteed, and the problem that the vibration reduction system and the energy feedback efficiency of a traditional energy feedback suspension system are difficult to consider at the same time is solved.
