<p>The various embodiments of the present invention provide an automatic voltage optimization system using toroidal transformer. The system comprises a first transformer, a second transformer, a switching matrix, a microcontroller for calculating an operating condition to regulate an operation of switching matrix and an inrush current limiter for limiting magnetizing current flowing into the transformer, when the primary is connected to input voltage. The first transformer and the second transformer are controlled by the switching matrix to maintain a target of 220 V or any desired voltage. The switching matrix comprises a plurality of switching devices. The microcontroller selects a preset switching sequence to select and operate a plurality of switches based on the calculated operating condition.</p> |
