| 摘要 |
The invention relates to a electrical/electronic apparatus, without dielectric coolants or oils, which is used to power electric motors and which alters the frequency, voltage, current and power parameters of the electric signals. The apparatus is connected to electric signals originating from power sources or networks via terminals of input windings wound around magnetic circuits which alter the voltage and the current of the signal originating from the sources or via the terminals from a filtering means containing inductors and capacitors. These windings or filtering means are connected internally to electrical speed-control systems which alter the frequency of the signal, and, subsequently, using special arrangements of windings and switching systems, multiple voltages, currents and powers are generated in the signal being supplied to the motors or required loads via different output terminals. |
