The utility model discloses electricity-saving appliance's working process as follows:

For example, when the voltage and/or current of the first primary coil L1-1 of the a-phase power supply is changed and the input C-phase power supply of the first secondary coil L3-1 connected thereto through the iron core is not changed, the voltage and/or current of the first secondary coil L3-1 is not changed, so the speed of change of the voltage and/or current of the first primary coil L1-1 is suppressed by the first secondary coil L3-1, whereby the influence of the abrupt change of the voltage and/or current on the three-phase power supply can be significantly reduced.
And at the in-process of three-phase power transmission electric energy, except single-phase short circuit, the three-phase short circuit in addition, fault conditions such as double-phase short circuit, for this reason, the utility model discloses negative feedback coil assembly and control circuit have still been set up in the electricity-saving appliance.

When the voltage and/or current of one or more power supplies of the three-phase transformer coil assembly is lower than the lower limit of a set value, corresponding first driving information, second driving information and third driving information are obtained, the drive circuit is controlled and converts the received information to obtain first on-off information, second on-off information and third on-off information, the on/off control of the first switching element K1, the second switching element K2 and the third switching element K3 is performed to reduce the conduction angles of the first switching element K1, the second switching element K2 and the third switching element K3, thereby shortening the conduction time of the negative feedback coil group, when the conduction time of the negative feedback coil is shortened, the voltage of the negative feedback coil is reduced, the magnetic flux of the iron core is positively fed back, so that the voltage and/or current of the primary coil is rapidly increased, and the voltage is increased under the positive feedback effect of the negative feedback coil.
