Can capacitors be used as energy storage in a drive system?

This document describes the integration of capacitors with SINAMICS DCP as energy storage into a drive system. To read this application manual, fundamental knowledge of drive technology and the contents of the SINAMICS DCP documentation /1, /2 are required.

What are supercapacitors & EDLC?

Supercapacitors also known ultracapacitors and electric double layer capacitors (EDLC) are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.

How do you measure the capacitance of a supercapacitor?

Supercapacitors have such large capacitance values that standard measuring equipment cannot be used to measure the capacity of these capacitors. Capacitance is measured per the following method: Charge capacitor for 30 minutes at rated voltage. Discharge capacitor through a constant current load. Measure voltage drop between V1 to V2.

How do I ship a Sirius capacitor module?

Sirius Capacitor Modules are shipped out via Air and Sea. Carefully remove the nails from all the four sides of the wooden box and open it. Remove the foam and shrink wrap and open the carton box and lift the Module manually. Carefully remove the Module from the pallets after cutting the packing strip holding the Modules to the shipping pallets.

What is a buck boost capacitor?

Due to the Buck-Boost technology of the SINAMICS DCP, the achievable voltage at the capacitor lies between 0 and 800 V (without overvoltage range); thus the storable energy is considerably higher in comparison to a pure Buck system (maximum DC-link voltage in the storage device, typically approx. 600 V).

How are the capacitors & sinamics DCPS integrated?

The capacitors and SINAMICS DCPs are integrated as needed with a pre-charging input circuit, contactors, and DC fuses. Details can be found in the documentation /1.
