A power generator is a device that converts mechanical energy into electric current. They are commonly used to power household appliances during an electrical outage.

The basic principle of generators is that the mechanical input (the engine) provides a steady stream of torque that causes the movement of electric charges in a set of windings. This induced current flows through an external circuit that can be sized to meet the appliance’s power requirements.
There are several types of generators: dynamos, alternators, and inverters. All three produce alternating current (AC), which reverses its polarity in 50 or 60 cycles per second.
Dynamos: One of the first practical electric generators was invented by Frenchman Hippolyte Pixii in 1832. Its commutator reversed the connection of the rotating armature wire to the circuit every 180deg rotation, producing a pulsing DC current.
Alternators: The rotor and stator of an alternator are connected together to create an internal DC source, often using induction or permanent magnets. They may be a single part in large generators or separate in smaller units.
Inverters: A combination of an alternating voltage generator and a rectifier that produces direct current is also called an inverter. It is more efficient than a synchronous generator and typically uses fewer parts.
Portables: A portable generator can be moved to deliver electricity in different locations and is sometimes used during camping trips. It is lighter than a standby generator and usually runs on gasoline.
Before you use a generator to supply power, check its labels and other information to ensure it will be able to handle the load. Avoid buying generators from unreputable manufacturers, as they are prone to producing poor power quality that could damage electronics and major appliances.
