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.
The key selection criterion for the aluminum capacitor is the needed ripple current, which corresponds to the 8 kHz to 20 kHz high-frequency ripple currents generated by the inverter. To maximize its operating life, the aluminum capacitor should be located on the coolest possible area of the PCB.
The key selection criterion for the aluminum capacitor is the required ripple current. The ripple current consists of two components, a low-frequency ripple (50 Hz to 200 Hz) from the input and a high-frequency component from the inverter, typically 8 kHz to 20 kHz.
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.
