Inverter duty transformer is also called as Solar Transformer & Step-up Transformer. These transformers are usually used in grid-tied photovoltaic solar power applications, to provide galvanic isolation, step-up the voltage and transfer energy back to the utility grid.
Most of the grid-tied photovoltaic solar power plants include a inverter duty transformer in their voltage/power transfer cycle. The photovoltaic modules consists of photovoltaic cells which absorbs the photons emitted by incident sun rays thereby generating flow of electrons.
The current generated is usually direct current (DC). This direct current is then provided as an input to an invertor which converts the DC to an alternating current (AC). However the voltage generated by this inverter is in few kilo volts (KV) which cannot be transferred to the power grid for further distribution and usage. The power grid mostly taps voltages in the range of 11kV, 22 kV, 33 kV. This is where the inverter duty transformer plays a major role in stepping up the voltage to the required level.
