A power inverter is a device that changes direct current (DC) to alternating current (AC). Learn about the input and output voltages, waveforms, and technical standards of different types of inverters, such as square wave, sine wave, and modified sine wave.
Learn about the history, operation and advantages of switched-mode power supply (SMPS), an electronic power supply that converts electrical power efficiently. SMPS uses a switching regulator to vary the output voltage and current by switching ideally lossless storage elements.
An AC-to-AC converter is a device that converts an AC waveform to another AC waveform with different voltage and frequency. Learn about the types, applications and topologies of AC-to-AC converters, such as cycloconverters, matrix converters and voltage controllers.
A rotary converter is a mechanical device that can convert alternating current (AC) to direct current (DC) or vice versa. It consists of a rotating armature with slip rings and field coils, and was used for railway electrification and industrial applications before solid state rectifiers.
Power electronics is the control and conversion of electric power with semiconductor switching devices. Learn about the history of power electronics, from mercury arc valves to MOSFETs and IGBTs, and the types of power electronic devices and applications.
The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters, due to the conversion from DC to AC rather than the voltage change. The output frequency and waveform of an inverter may not accurately replicate that supplied by mains electricity ...
Utilization categories are defined by IEC standards and indicate the type of electrical load and duty cycle of the loads for switchgear selection. AC-15 is the category for control of AC electromagnetic loads, such as relays, solenoids, and contactors.
A rectifier is a device that converts AC to DC current. Learn about different rectifier devices, such as vacuum tubes, diodes, thyristors and silicon-controlled rectifiers, and how they are used in various circuits and systems.
