  2. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply ) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.

  3. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    Waveform produced by a cigarette lighter 12 volt DC to 120 V AC 60 Hz inverter. The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a repeated voltage step sequence of zero, peak positive, zero, peak negative, and again zero.

  4. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    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 ...

  5. DC-to-DC converter - Wikipedia

    en.wikipedia.org/wiki/DC-to-DC_converter

    DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).

  6. Vibrator (electronic) - Wikipedia

    en.wikipedia.org/wiki/Vibrator_(electronic)

    Schematic diagram of a typical circuit to convert low voltage DC to high voltage DC. The vibrator was a device with switch contacts mounted at the ends of flexible metal strips. In operation, these strips are vibrated by an electromagnet, causing the contacts to open and close rapidly.

  7. Rotary converter - Wikipedia

    en.wikipedia.org/wiki/Rotary_converter

    1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.

  8. H-bridge - Wikipedia

    en.wikipedia.org/wiki/H-bridge

    Most DC-to-AC converters (power inverters), most AC/AC converters, the DC-to-DC push–pull converter, isolated DC-to-DC converter [2] most motor controllers, and many other kinds of power electronics use H bridges. In particular, a bipolar stepper motor is almost always driven by a motor controller containing two H bridges.

  9. Grid-tie inverter - Wikipedia

    en.wikipedia.org/wiki/Grid-tie_inverter

    A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel , wind turbine , hydro-electric , and the grid.
