6 FAQs about [Inverter circuit capacitor selection]

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

Selection of the best capacitor for a power inverter or other DC link application usually begins with a comparison of the required capacitance and ripple currents. Make sure that the specs you are comparing are referenced to the same operational standards.

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.

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.

How big should a DC link capacitor be?

With electric vehicles, inverters are typically optimized for two things - power density and efficiency. Thus, DC link should not be any larger than what the requirements call for. The objective of this article is to help you better understand the role of the DC link capacitor and how to properly size it based off your requirements.

Why does a DC link capacitor have a ripple current ICAP?

We may infer from Figure 2 that the DC link capacitor’s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor.
