In addition, as shown in Figure 4, drive circuit 200 also comprises a damping battery Db in parallel with DC power supply Vdc, and it is one and can be repeated discharge and recharge and have the rechargeable battery of damping function, such as capacitor batteries or soda acid resonance battery.
Whereby, drive circuit 200 control contact U, the V of three-phase coil R, S, T, contact V, W, contact W, U in turn with DC power supply Vdc electric coupling, with by turn to the wherein two-phase coil excitation of three-phase coil R, S, T, drive the first motor 52 and the second motor 53 to operate with motor information simultaneously, and flywheel driven 54 accelerates to rotate and energy storage, now, first DC support electric capacity C1 can the output voltage of stable dc power supply Vdc, makes its voltage fluctuation keep can stably supplying three-phase coil R, S, T in allowed limits.
Moreover, as shown in Figures 4 and 5, such as when drive circuit 200 connects coil R, S and DC power supply Vdc by the upper switch U+ of brachium pontis 21 and the lower switch V-of brachium pontis 22, coil R, S are rotated by the excitatory and rotor relative stator of ordering about the first motor 52 and the second motor 53.Then, drive circuit 200 makes DC power supply Vdc and coil R, S not connect, and emat coil S, T and DC power supply Vdc connect, with excitatory to coil S, T.Now, as shown in Figures 6 and 7, coil R, S will produce back electromotive force e1, e2 because of moment not conducting, wherein, back electromotive force e1 on coil R is by the discharge loop (shortest path) following neutral point Np, the second Support Capacitor C3, the second free-wheel diode D2 of free-wheel diode group 24 is formed, second Support Capacitor C3 is discharged, simultaneously, back electromotive force e2 on coil S, by following the first free-wheel diode D1 of free-wheel diode 25, the discharge loop (shortest path) of the second Support Capacitor C2, neutral point Np formation, discharges to the second Support Capacitor C2.Therefore, above-mentioned second Support Capacitor C2, C3 accepts back electromotive force e2, e1 of exchanging respectively, and convert back electromotive force e2, e1 to direct current energy, and produce damping effect and (also turn direct current by interchange, to absorb back electromotive force e2, e1 completely, and there is maximum power transfer), then by second Support Capacitor C2, C3, electric energy (namely charging to damping battery Db) is discharged to damping battery Db, back electromotive force e2, e1 are reclaimed with the form of direct current and is stored in damping battery Db.
In like manner, when coil S, T are by after excitatory, from with DC power supply Vdc connect state become do not connect state time, the back electromotive force that coil S, T produce instantaneously also will discharge to second Support Capacitor C2, C3 via corresponding free-wheel diode group in the above described manner, by second Support Capacitor C2, C3, electric energy (namely charging to damping battery Db) is discharged to damping battery Db again, and the back electromotive force that coil S, T produce instantaneously recovery is stored in damping battery Db.Whereby, except three-phase coil R can be avoided, S, outside the high pressure back electromotive force that T produces instantaneously directly impacts DC power supply Vdc, by three-phase coil R, S, the back electromotive force of the upper generation of T is via free-wheel diode group 24, 25, 26 are recycled to the second Support Capacitor C2, C3, be stored in damping battery Db again, make back electromotive force can not flow through the brachium pontis 21 of drive circuit 200, 22, 23 (on, the free-wheel diode D of lower switch), make the brachium pontis 21 of drive circuit 200, 22, 23 not reason back electromotive force and heating up, but also back electromotive force can be avoided by brachium pontis 21, 22, with input brachium pontis 21 during 23 output, 22, the DC power supply Vdc of 23 clashes, and cause electric energy loss heat-dissipating for no reason and cause the problem that drive circuit 200 heats up.
And, its current potential is higher than DC power supply Vdc usually to reclaim the back electromotive force (voltage) be stored in damping battery Db, therefore damping battery Db preferentially can supply electrical power to the first motor 52 and the second motor 53 that driven circuit 200 drives, and increases the endurance of DC power supply Vdc.
