Abstract— Aluminum electrolytic capacitors are widely used in all types of inverter power systems, from variable-speed drives to welders to UPS units. This paper discusses the considerations involved in selecting the right type of aluminum electro-lytic bus capacitors for such power systems.

What are aluminum Elec-trolytic capacitors used for?

One of the main application classes of aluminum elec-trolytic capacitors is input capacitors for power invert-ers. The aluminum electrolytic capacitor provides a unique value in high energy storage and low device impedance. How you go about selecting the right ca-pacitor or capacitors, however, is not a trivial matter.

Can aluminum electrolytic capacitors withstand overvoltage?

Aluminum electrolytic capacitors can generally withstand extreme overvoltage transients of limited energy. Application of overvoltage more than about 50 V beyond the capacitor’s surge voltage rating causes high leakage current and a constant-voltage operating mode quite like the reverse conduction of a zener diode.

Which electrolytic capacitor is best for AC & RF applications?

This makes aluminum electrolytics the choice for high-capacitance applications like rectification filters and power hold up where more capacitance is a bonus. Ceramic capacitors are not polarized and therefore can be used in AC applications. The low DF and high capacitance stability of Class 1 and 2 are especially suited to AC and RF applications.

What are the tolerances for aluminum electrolytic capacitors?

While tolerances of ±5% and ±10% are routine for ceramic capacitors, ±20% and –10% +50% are the norms for aluminum electrolytic. This makes aluminum electrolytics the choice for high-capacitance applications like rectification filters and power hold up where more capacitance is a bonus.

What is the function of aluminum capacitor in a switch mode inverter?

The aluminum capacitor is used as an energy buffer to ensure stable operation of the switch mode inverter driving the motor. The aluminum capacitor also functions as a filter to prevent high-frequency components from the switch mode inverter from polluting the mains voltage.
