A voltage regulator is an electricity regulator designed to automatically maintain a constant voltage level.It may use an electromechanical mechanism, or passive or active electronic components....
 with at least one other function to improve power quality (e.g. noise suppression, transient impulse protection, etc.).

The terms "power conditioning" and "power conditioner" can be misleading, as the word "power" refers to the electricity
Electricity

Electricity is a general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena such as lightning and static electricity, but in addition, less familiar concepts such as the electromagnetic field and electromagnetic induction....

Electric power

Electric power is defined as the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt .When electric current flows in a circuit, it can transfer energy to do mechanical work or work ....

Power conditioners can vary greatly in specific functionality and size, with both parameters generally determined by the application. Some power conditioners provide only minimal voltage regulation while others provide protection from half a dozen or more power quality problems. Units may be small enough to mount on a printed circuit board

 or large enough to protect an entire factory. Small power conditioners are rated in volt-amps (VA) while larger units are rated in kilo-volt-amps (kVA).

While no single power conditioner can correct all power quality problems, many can correct a variety of them.

It is common to find audio power conditioners that only include an electronic filter

Active power conditioner

Active power conditioner refers to power electronic devices that are used in industry or commercial facilities to improve electrical power quality and remove behaviours that cause losses and disruptions, such as harmonics, reactive power, flicker and resonance in low to high voltage supply lines....
