Detailed explanation-1: -Transformers use electromagnetic induction to change the voltage and current. This change is called transformer action, and describes how the transformer changes an AC signal from its primary to its secondary component (like in the equation above).

Detailed explanation-2: -A transformer’s main function is to step-up or step-down the voltage from the primary to the secondary windings. This is done simply by adjusting the ratio of coils on one side to the other.

Detailed explanation-3: -An inverter transformer is commonly used in an inverter that converts DC power to AC power. DC is converted to AC, and the voltage is boosted using an inverter transformer.

Detailed explanation-4: -Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits.

Detailed explanation-5: -Transformers step up (increase) or step down (decrease) AC voltage using the principle of electromagnetic induction-mutual induction. A changing current in the primary coil induces an e.m.f in the secondary.
