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]
A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.
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.
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.
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.
An example CMOS digital phase frequency detector. Inputs are R and V while the outputs U p and D n feed to a charge pump. A phase detector suitable for square wave signals can be made from an exclusive-OR (XOR) logic gate. When the two signals being compared are completely in-phase, the XOR gate's output will have a constant level of zero.

The first locomotive with a phase converter (only for demonstration purposes) The Kandó phase converter (1933) The "Kandó" locomotive, the first locomotive using a phase converter system. At the beginning of the 20th century, there were two main principles of electric railway traction current systems: DC system; 16⅔ Hz single phase system
