An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
A microwave (6 to 18 GHz) Phase Shifter and Frequency Translator. A phase shift module is a microwave network module which provides a controllable phase shift of the RF signal. [1] [2] [3] Phase shifters are used in phased arrays. [4] [5] [6]

Switched-mode power supplies have become widespread in the early twenty-first century; they are smaller and lighter than the once-universal transformer converters, and are often designed to work from AC mains at any voltage between 100 and 250 V. Additionally, because they are typically rectified to operate at a DC voltage, they are minimally ...
Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time.
When the amplifier's 180° of phase inversion is added to this, the result is a full 360° at the f i intercept, indicated by the dashed vertical line. At that intercept, 1/β = A OL for a loop gain of A OL β = 1. Oscillation will occur at the frequency f i because of the 360° phase shift, or positive feedback, and the unity gain. [6]
A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies , sometimes as high as 90–95%, while being electrically simple circuits.
400 MVA 220/155 kV phase-shifting transformer.. A phase angle regulating transformer, phase angle regulator (PAR, American usage), phase-shifting transformer, phase shifter (West coast American usage), or quadrature booster (quad booster, British usage), is a specialised form of transformer used to control the flow of real power on three-phase electric transmission networks.
