The invention relates to a three-floated-gyro magnetic levitation control circuit. The three-floated-gyro magnetic levitation control circuit comprises an alternating-current power source 1, a direct-current power source 2, a leakage circuit, multiple identical-structured switch circuits 4, multiple identical-structured bridge circuits 5, a differential amplification circuit 6, a demodulation circuit 7, a filter circuit 8, an analog-to-digital conversion circuit 9 and a digital signal processor 10. The three-floated-gyro magnetic levitation control circuit has the advantages that by the aid ofswitch control time sequence, magnetic levitation coil counter potential interference suppression is achieved, circuit noise is suppressed greatly, position detection and force application efficiencyis increased, and accordingly magnetic levitation interference torque is lowered, and gyro precision is further improved; meanwhile, the leakage circuit does not affect position detection at all, anda direct-current power source gating switch is in a disconnected state during the position detection and does not affect the bridge circuits.
