Output power is handled by replaceable phase modules, which are cooled by Parker’s advanced 2-phase cooling system. Each module contains IGBT power semiconductors, DC bus capacitors, and gate drive circuitry.

Are energy storage technologies viable for grid application?

Energy storage technologies can potentially address these concerns viably at different levels. This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.

What makes a PCs a synchronous generator?

The PCS must be able to syn-chronize with the grid frequency and provide a stable output – appearing to the grid to be a synchronous gen-erator. It responds to changing conditions, providing energy at a controlled ramp rate, but also injects power quickly to correct short term frequency fluctuations.

Does a PCs need a thermal management system?

Given that the PCS is usually operational 24/7, and in a range of potentially extreme environmental conditions, a good thermal management system is included – both for the inverters and for the ancillary components. The 890GT-B is available in ratings to 2200 kVA, and for storage arrays up to 1200 volts DC.
