Power Modulator are those devices which are used to convert the given electrical power into the desired power for e.g. the supplied power is of ac form than and required is dc than we will employ rectifier power modulator for converting ac power into dc , and if the given form is dc and required is ac than we will employ a inverter power modulator.

Transformers are static devices who transfer electric power from one circuit to another with changed voltage levels but keeping the system frequency constant. They are of two types step up and step down. Transformer has two windings one is primary and other is secondary winding and these are both placed in the transformer tank.
