An example of a voltage doubler is found in the input stage of switch mode power supplies containing a SPDT switch to select either 120 V or 240 V supply. In the 120 V position the input is typically configured as a full-wave voltage doubler by opening one AC connection point of a bridge rectifier, and connecting the input to the junction of ...
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.
Two-stage charge pump with DC voltage supply and a pump control signal S 0 Dickson charge pump with diodes Dickson charge pump with MOSFETs PLL 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 ...
A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
Liquid-ring pumps are typically used as vacuum pumps, but can also be used as gas compressors. The function of a liquid-ring pump is similar to a rotary vane pump, with the difference being that the vanes are a rigid part of the rotor and churn a rotating ring of liquid to form the compression-chamber seal. They are an inherently low-friction ...
