A voltage regulator is designed to automatically maintain a constant voltage level. A voltage regulator may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.

An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected. Isolation transformers block transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to pass. Suitably designed isolation transformers block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.

An AC power conditioner is the typical power conditioner that provides "clean" AC power to sensitive electrical equipment. Usually this is used for home or office applications and has up to 10 or more receptacles or outlets and commonly provides surge protection as well as noise filtering. 'Power line conditioners take in power and modify it based on the requirements of the machinery to which they are connected. Attributes to be conditioned are measured with various devices, such as, Phasor measurement units. Voltage spikes are most common during power storms or other malfunctions in the main power lines. The surge protector stops the flow of electricity from reaching a machine by shutting off the power source. The term "Power Conditioning" has been difficult to define historically. However, with the advances in power technology and recognition by IEEE, NEMA, and other standards organizations, a new actual engineering definition has now been developed and accepted to provide an accurate depiction of this definition. "Power Conditioning" is the ability to filter the a.c. line signal provided by the power company. "Power Regulation" is the ability to take a signal from the local power company, turn it into a d.c. signal that will run an oscillator, which generates a single frequency sine wave, which is determined by your local area needs, is fed to the input stage of power amplifier, and is then output as what is specified as the ideal voltage present at any standard wall outlet.
