Electronic Transformer

Matix converter can be used with a high frequency ac link to make low frequency transformer.

The circuit presented here uses MOSFET as switches and EE70 ferrite core transformer as AC link. Transformation ratio is directly prepotional to turns ratio of EE70. If EE 70 have 1:1 turns ratio the curcuit will act as 1:1 isolation transformer. The main adventage of this topology is its low frequency response. We can use this electronics transformer DC to 200Hz.
