Where electrical isolation is not required between the supply and load, one can match the supply voltage to load voltage through a step up or step down autotransformer. Autotransformers have a portion of their winding common to the input (supply) side and output (load) side and hence cannot be used...

In addition to load demands, power company regulations may limit the current surge or voltage fluctuation that can be imposed on the power supply during motor starting. Many starters apply reduced voltage to motor windings; primary resistor, primary reactor, autotransformer, and solid state. Part...
