  2. Load regulation - Wikipedia

    en.wikipedia.org/wiki/Load_regulation

    Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

  3. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    In either case, the power wasted in the pass device is very little and almost all the power is transmitted to the load. Thus the efficiency of a switched-mode power supply is remarkably high – in the range of 70–90%. Switched mode regulators rely on pulse-width modulation to control the average value of the output voltage. The average value ...

  4. Voltage regulation - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulation

    In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line. Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load ...

  5. Regulated power supply - Wikipedia

    en.wikipedia.org/wiki/Regulated_power_supply

    A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

  6. Line regulation - Wikipedia

    en.wikipedia.org/wiki/Line_regulation

    A low line regulation is always preferred. In practice, a well regulated power supply should have a line regulation of at most 0.1%. [1] In the regulator device datasheets the line regulation is expressed as percent change in output with respect to change in input per volt of the output. Mathematically it is expressed as:

  7. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Seen with an oscilloscope, the domestic power supply in North America would look like a sine wave, oscillating between −170 volts and 170 volts, giving an effective voltage of 120 volts RMS. [18] Three-phase electric power is more efficient in terms of power delivered per cable used, and is more suited to running large electric motors. Some ...

  8. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An integrated power supply is one that shares a common printed circuit board with its load. An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics ...

  9. Linear regulator - Wikipedia

    en.wikipedia.org/wiki/Linear_regulator

    When the supply voltage is less than about 2 V above the desired output voltage, as is the case in low-voltage microprocessor power supplies, so-called low dropout regulators (LDOs) must be used. When the output regulated voltage must be higher than the available input voltage, no linear regulator will work (not even a low dropout regulator).
