  2. Capacitance multiplier - Wikipedia

    en.wikipedia.org/wiki/Capacitance_multiplier

    A capacitance multiplier is designed to make a capacitor function like a much larger capacitor. This can be achieved in at least two ways. An active circuit, using a device such as a transistor or operational amplifier; A passive circuit, using autotransformers. These are typically used for calibration standards.

  3. Electrical element - Wikipedia

    en.wikipedia.org/wiki/Electrical_element

    To model the nonideal behavior of a real circuit component may require a combination of multiple ideal electrical elements to approximate its function. For example, an inductor circuit element is assumed to have inductance but no resistance or capacitance, while a real inductor, a coil of wire, has some resistance in addition to its inductance ...

  4. Voltage doubler - Wikipedia

    en.wikipedia.org/wiki/Voltage_doubler

    Figure 2.Greinacher circuit. The Greinacher voltage doubler is a significant improvement over the Villard circuit for a small cost in additional components. The ripple is much reduced, nominally zero under open-circuit load conditions, but when current is being drawn depends on the resistance of the load and the value of the capacitors used.

  5. Switched capacitor - Wikipedia

    en.wikipedia.org/wiki/Switched_capacitor

    A switched capacitor (SC) is an electronic circuit that implements a function by moving charges into and out of capacitors when electronic switches are opened and closed. Usually, non-overlapping clock signals are used to control the switches, so that not all switches are closed simultaneously.

  6. Vienna rectifier - Wikipedia

    5. Voltage between mains midpoint M and the output voltage midpoint 0. Note: Inner mains inductance is not considered, and therefore the voltage across the filter capacitors is equal to the mains voltage. Figure 3 shows the system behaviour, calculated using the power-electronics circuit simulator. [11]

    Video of the terrifying incident ran on the station’s morning news program, capturing the sound of at least eight gunshots, then screams, and briefly showed Flanagan, 41, holding a gun.

  8. Electrical network - Wikipedia

    en.wikipedia.org/wiki/Electrical_network

    A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...
