Comparison of DC link current and stator phase current in inverter

The results show that both of phase current and DC link current have a good capability to find the faulty switch or switches. But in practice, a DC link current sensor will be an extra cost if the phase current sensors are used for control. However the cost will reduce when the DC link current is used for analyses since it requires only one sensor.

6 FAQs about [Relationship between DC cabinet and inverter]

What is a DC-AC inverter?

An inverter that converts a direct current into an alternating current is called a DC-AC inverter. However, the term “inverter” generally refers to the equipment that combines an AC-DC converter (that changes an alternating current into a direct current) and a DC-AC inverter so as to be able to generate arbitrary frequencies and voltages. Figure

Are current source type inverters still used?

However, current source type inverters are still in use for some applications. For example, in high-voltage direct current (HVDC) transmission, a DC current travels a long distance before being converted back into AC. This means a DC current is supplied via a large reactor.

Which type of inverter is used for HVDC?

Since the DC side must be treated as a current source, a current source type inverter is used for HVDC applications. Thyristors also remain in use in ultra-large inverters. Because of the reverse-blocking characteristics of thyristors, a current-mode configuration is sometimes used for such inverters.

How to design an energy storage cabinet?

The following are several key design points: Modular design: The design of the energy storage cabinet should adopt a modular structure to facilitate expansion, maintenance and replacement. Battery modules, inverters, protection devices, etc. can be designed and replaced independently.
