Boost Transformer and Line Reactor 1

[ServoWizard]

Hello,

Along with modifying the voltage does a boost transformer in effect accomplish the same task as a line reactor?

In terms of reducing harmonics, generally yes - for the same amount of impedance.

A boost transformer generally will not perform as well as a series reactor. The idea of a boost transformer is that for small changes of voltage an autotransformer costs less and has less in the way of losses and voltage drop.

I agree with mc5w that if this "boost" transformer is an autotransformer it will probably have very low impedance - and might not work as well as a line reactor for reducing harmonics. That's why I qualified my answer.

You'd be better off with a standard two-winding transformer if you need to change voltage as well as provide a buffering impedance.
