6 FAQs about [Inverter capacitor selection parameters]

How do I choose the best capacitor for a power inverter?

What is a DC link capacitor in a power inverter?

The DC link capacitor is applied from positive to negative after rectification. In a power inverter, a DC link capacitor is placed in parallel with the input to minimize the effects of voltage variations as the load changes. The DC link capacitor also provides a low-impedance path for ripple currents generated by power switching circuits.

Which capacitors are used in inverter applications?

A general approach for ripple current characterization is provided. Based on these characteristics, the two capacitor types suitable for this purpose, the electrolytic and film capacitors, used in inverter applications are reviewed. Capacitor power loss and voltage ripple calculation are provided for both types.

Are aluminum electrolytic bus capacitors a good choice for inverter power systems?

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 the specifications associated with capacitor selection?

Some of the specifications associated with capacitor selection can be confusing, even if you have a basic understanding of what the terms mean. However, that's still a good place to start. We know that for DC link applications, capacitors should have very low ESR, low self-inductance and high ripple-current ratings.

How much capacitor nameplate CV rating should a 3 phase inverter use?

For three-phase inverters at any DC bus voltage, for films and electrolytics, respectively, a rule of thumb is that about 5 and 50 millicoulombs of capacitor nameplate CV rating will be required per amp of ripple current.
