4 FAQs about Inverter DC voltage regulation

Why does a regulator shut down a DC-link inverter?

During network contingencies, this voltage increases and exceeds the safe limit which causes the protection scheme to shut down the inverter. As this phenomenon decreases a system's reliability, a regulator is designed to control the dc-link voltage during a voltage limit violation and thereby protecting the inverter from shutting down.

What is the DC-link voltage of an inverter?

It is shown that, during normal operation of the inverters, the dc-link voltage is constant 400 V, starts increasing at t = 1 s after unintentional islanding (case 3) and reaches its maximum Vdc voltage (700 V).

Does circulating power violate DC-link voltage limit?

This circulating power may violate the dc-link voltage limit and, as a result, the protection scheme may shut down the inverter and reduce the microgrids reliability. This paper proposes a regulator for controlling the dc-link voltage of the microgrid's inverter during a period of circulating power.

How do grid-forming inverters achieve power support and voltage optimization?

This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.
