  2. Charge pump - Wikipedia

    en.wikipedia.org/wiki/Charge_pump

    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.

  3. MAX232 - Wikipedia

    en.wikipedia.org/wiki/MAX232

    MAX232 chip in DIP-16 package The die of a MAX232 MAX232 pinout: Red: power, Yellow: charge pump capacitors, Blue: outputs, Green: inputs, Pins 9–12: TTL/CMOS I/O voltages. The MAX232 is an integrated circuit by Maxim Integrated Products, now a subsidiary of Analog Devices, that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic ...

  4. Water capacitor - Wikipedia

    en.wikipedia.org/wiki/Water_capacitor

    Water capacitors, being self-discharging, (for totally pure water, only thermally ionized, at 25 °C (77 °F) the ratio of conductivity to permittivity means that self-discharge time is circa 180μs, faster with higher temperatures or dissolved impurities) usually cannot be made to store enough residual electrical energy to cause serious bodily ...

  5. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.

  6. Pentair - Wikipedia

    en.wikipedia.org/wiki/Pentair

    Pentair plc (PNR) is an American water treatment company incorporated in Ireland with tax residency in UK, with its main U.S. office in Golden Valley, Minnesota. [6] Pentair was founded in the US, with 65% of company's revenue coming from the US and Canada as of 2017.

  7. Motor capacitor - Wikipedia

    en.wikipedia.org/wiki/Motor_capacitor

    A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...

  8. Hydraulic analogy - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_analogy

    The mass of the rotor and the surface area of the vanes restricts the water's ability to rapidly change its rate of flow (current) through the pump due to the effects of inertia, but, given time, a constant flowing stream will pass mostly unimpeded through the pump, as the rotor turns at the same speed as the water flow. The mass of the rotor ...

  9. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    A discharged or partially charged capacitor appears as a short circuit to the source when the source voltage is higher than the potential of the capacitor. A fully discharged capacitor will take approximately 5 RC time periods to fully charge; during the charging period, instantaneous current can exceed steady-state current by a substantial ...
