6 FAQs about [Application of energy storage inductor in inverter]
Is DC energy storage inductor a constant current source?
At present, it has received certain attention and research in wind power generation [ 7 ], photovoltaic grid connection [ 8 ], motor drive [ 9] and other fields. However, the current of the DC energy storage inductor is not a constant current source, but a DC voltage source charges the DC energy storage inductor to generate current output.
What is the rate of energy storage in a Magnetic Inductor?
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
What is voltage source inverter (VSI)?
Voltage source inverter (VSI) has the advantages of simple structure and flexible control, and is widely used in electric energy conversion occasions such as motor drive and new energy power generation [ 1 ].
How does an inductor work?
The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value. In each case, the inductor prevents the ripples from influencing the regulated DC.
What is a current source inverter?
Compared with the voltage source inverter, the current source inverter has the boosting characteristics, and the AC side does not need a complex and bulky filter unit, but it also has the problem of current control of the DC energy storage inductor.
What are the characteristics of a practical inductor?
The exponential characteristics of a practical inductor differ from the linear behavior of ideal inductors; both store energy similarly–by building up their magnetic fields. These magnetic fields have undesirable effects on the inductors and nearby conductors, causing several safety hazards.
