Selecting dc-link capacitors for inverters

The capacitor voltage rating must exceed the worst-case peak bus voltage as might arise under "high-line" mains conditions, maximum solar-panel output voltage, etc. Low-ESR aluminum electrolytic capacitors are rated only up to 500 Vdc, so they may need to be connected in series with balancing resistors.

6 FAQs about [Inverter output voltage series capacitor]

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 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.

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 are the components of a IC switched capacitor inverter?

The control circuit consists of an oscillator and the switch drive signal generators. Most IC switched capacitor inverters and doublers contain all the control circuits as well as the switches and the oscillator. The pump capacitor, C1, and the load capacitor, C2, are external.

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.

How to control a switched capacitor inverter/doubler?

The most straightforward is to follow the switched capacitor inverter/doubler with a low dropout (LDO) linear regulator. The LDO provides the regulated output and also reduces the ripple of the switched capacitor converter. This approach, however, adds complexity and reduces the available output voltage by the dropout voltage of the LDO.
