Technical FAQs 4

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.

What is a switched capacitor inverter?

Switched capacitor inverters are low cost and compact and are capable of achieving efficiencies greater than 90%. Obviously, the current output is limited by the size of the capacitors and the current carrying capacity of the switches. Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum.

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 to sizing capacitors for inverter bus link applications?

The first step in sizing capacitors for inverter bus link applications should be to understand how much bus link capacitance is required for a given inverter design. The biggest design limitation for electrolytic capacitors in inverter applications has been the amount of ripple current that the electrolytic capacitor can sustain.
