DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies.
Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine.
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
