4 FAQs 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 does a DC inverter work?

The inverter essentially converts the input DC voltage into voltage pulses through pulse width modulation (PWM) such that the average voltage during a given switching period equals the desired voltage command . The motor then generates current and torque which are applied to the mechanical system within which the electric motor drive is used.

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.
