The two most common switched capacitor voltage converters are the voltage inverter and the voltage doublercircuit shown in Figure 4.1. In the voltage inverter, the charge pump capacitor, C1, is charged to the input voltage during the first half of the switching cycle.
Capacitor conversion involves replacing a capacitor with a different type or value while maintaining circuit function. This may be necessary for repairs, upgrades, or due to availability. This tool helps you find suitable replacement capacitors. A capacitor itself does not directly convert AC (Alternating Current) to DC (Direct Current).
Adding regulation to the simple switched capacitor voltage converter greatly enhances its usefulness in many applications. There are three general techniques for adding regulation to a switched capacitor converter. The most straightforward is to follow the switched capacitor inverter/doubler with a low dropout (LDO) linear regulator.
(This is key to switched-capacitor converters) element (e.g. inductor) and use that to charge vc to a fnal voltage > Vs. Otherwise the delivered charge limits us. Given appropriate switch implementations, SC converters are bidirectional. Consider “turning around” the converter above: 1) We can fx this with “interleaving”. a given allowed ripple.
Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum. Switched capacitor voltage converters do not maintain high efficiency for a wide range of ratios of input to output voltages, unlike their switching regulator counterparts.
Switched capacitor (SC) technology can be integrated into ICs and used for dc/dc converters, voltage inverters, voltage doublers, voltage dividers, and standalone dc/dc converters, ac/dc power supplies, and solar microinverters.
