  2. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    A 20-volt level was added in a revision named "class B" of the specification. [12] [13] The voltage range of the successor Pump Express Plus 2.0 is between 5 volts and 20 volts, with 0.5 volts steps. The Quick Charge 3.0 protocol supports finer-grain voltage levels with 0.2 volts steps and has a lower minimum voltage of approximately 3.3 volt.

  6. Pre-charge - Wikipedia

    en.wikipedia.org/wiki/Pre-charge

    Upon completion of pre-charging, the pre-charge resistance is switched out of the power supply circuit and returns to a low impedance power source for normal mode. The high voltage loads are then powered up sequentially. The simplest inrush-current limiting system, used in many consumer electronics devices, is a NTC resistor.

  9. Voltage multiplier - Wikipedia

    en.wikipedia.org/wiki/Voltage_multiplier

    Voltage multipliers can be used to generate a few volts for electronic appliances, to millions of volts for purposes such as high-energy physics experiments and lightning safety testing. The most common type of voltage multiplier is the half-wave series multiplier, also called the Villard cascade (but actually invented by Heinrich Greinacher ).
