For example, in the intelligent AC motor, the three-phase power is connected to the three-phase stator winding by three groups of gate.

The electric network non-power frequency is three-phase asymmetric.

A filter for filtering a three-phase electrical power waveform produces a three-phase output power waveform.

An improved embodiment of a three-phase converter is also disclosed.

The power supply circuit of the electricity meter receives a three-phase line voltage and converts the variable three phase line voltage to a constant DC output (26).
