Power source - electrical equipment designed to generate, store electrical energy or change its characteristics.

There are three main groups of power supplies:

Primary. The primary include converters of various types of energy into electrical energy, an example is a battery that converts chemical energy into electrical energy.
Secondary. These sources do not generate electricity themselves, but only serve to convert it in order to provide the required parameters (voltage, current, voltage ripple, etc.)
Tertiary. It is a power source for equipment that connects to a secondary power source.

Primary power sources include chemical current sources (galvanic cells, batteries, fuel cells) and the rest: photoelectric converters (solar battery), thermoelectric converters, electromechanical current sources, MHD generator, radioisotope energy sources.

Secondary power sources include: transformers and autotransformers of alternating voltage and current, vibration converters, pulse converters, voltage and current stabilizers, inverters, umformers (electric machine converter).
