"Перетворювальні" refers to processes or mechanisms that transform one form of energy or matter into another. This term is often used in various fields, including physics and engineering, to describe systems that convert energy types, such as electrical energy into mechanical energy. In the context of technology, "перетворювальні" devices, like перетворювачі (converters), play a crucial role in making energy usable for different applications. For example, a інвертор (inverter) converts direct current (DC) into alternating current (AC), enabling the use of solar energy in homes.
