Technical FAQs 4

What is a switched capacitor voltage converter?

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.

How many Ma can a switched capacitor inverter run?

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.

Which capacitor is used in IC switched capacitor voltage converter?

The pump capacitor, C1, and the load capacitor, C2, are external. Not shown in the diagram is a capacitor on the input which is generally required to ensure low source impedance at the frequencies contained in the switching transients. The switches used in IC switched capacitor voltage converters may be CMOS or bipolar as shown in Figure 4.9.

Can a single-source switched capacitor 13-level inverter maintain capacitor voltage balance?

Voltage stress of the components in the proposed structure. In this paper, a single-source switched capacitor 13-level inverter with a three-fold voltage gain has been presented. This converter can maintain capacitor voltage balance throughout the positive and negative half-period of the output voltage.
