Free Quote6 Frequently Asked Questions about “DC voltage utilization is the inverter”
What is DC voltage utilization ratio?
In addition to having fewer components and higher efficiency, the dc voltage utilization ratio of the inverter is 2.5 times that of the traditional inverter such as Neutral Point Clamped (NPC), FC, and Active NPC (ANPC).
How much voltage can an inverter output?
The inverter can output a fundamental voltage four times the dc-link voltage. However, there is no doubt that with the increase of the dc sources number, the cost of the entire system will increase significantly.
What are the advantages and disadvantages of a proposed inverter?
The higher operation efficiency can also be obtained, reaching 98.1%. With the same power, the proposed inverter has higher efficiency than other advanced inverters. In general, the proposed inverter has great advantages in the number of components, voltage stress of switching devices, dc voltage utilization and operation efficiency.
How many voltage levels can an inverter synthesize?
The proposed inverter can synthesize up to nine voltage levels with only ten switching devices and a flying capacitor (FC). To improve the operation efficiency, a hybrid-device topology based on Si and SiC is proposed. The total device cost of this inverter is much lower than the all-SiC-based inverter.
Does a 9-level inverter increase power loss?
It is worth noting that although the nine-level inverter in [ 23] obtains 1.5 times voltage gain with the lower components, it greatly increases the voltage stress of the switching devices and FC, which will not only increase power loss and cost, but also limit the inverter to high-voltage application.
What is the operation efficiency of an MLI inverter?
The higher operation efficiency can be obtained, reaching 98.3%. For comparison with the MLIs in [ 18, 20, 21 ], the dc voltage and power of the proposed inverter are set to 200 V and 400 W. The higher operation efficiency can also be obtained, reaching 98.1%.
