An actuator is a component of a machine that is responsible for moving or controlling a mechanism or system.
A transducer is a device that converts one form of energy to another.
A synchro is, in effect, a transformer whose primary-to-secondary coupling may be varied by physically changing the relative orientation of the two windings.
In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit.
In electronics, an analog-to-digital converter (ADC, A/D, A–D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone light entering a digital camera, into a digital signal.
In electronics, a digital-to-analog converter (DAC, D/A, D–A, D2A, or D-to-A) is a device that converts a digital signal into an analog signal.
A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
Switched-mode power supply
A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).
A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
Current sensing techniques
Current sensing is a vital task in electrical sector, where the current information is required for monitoring and control purposes.
An automatic or self-winding watch is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer's arm to provide energy to run the watch, making manual winding unnecessary.
