What happens when an inductor is saturated?
When the inductor enters saturation, it can store less energy and the ripple current increases – meaning that the efficiency will be reduced. At this point, the inductor is behaving more like a resistor than an inductor.
How does inductor behave when a steadily increasing current flows through it?
Energy in an Inductor When the current flowing through the inductor is increasing and di/dt becomes greater than zero, the instantaneous power in the circuit must also be greater than zero, ( P > 0 ) ie, positive which means that energy is being stored in the inductor.
Why does my vape burn my throat?
Increased levels of propylene glycol (compared to vegetable glycerin) has an increased hit. Smaller mouthpiece which narrows the airflow can cause a harsher throat hit. Dry hit, when the juice isn’t transferred to the atomizer coil, causes a burning hit.
What happens when the inductor is not saturated?
From the simulation waveform, we know that when the inductor is not saturated, the inductor current is a triangular wave with a certain slope. When the inductor is saturated, the inductor current waveform has significant distortion, which is caused by the decrease in the sense of saturation (see Figure 7).
How is the current of an inductor calculated?
The inductor current can be calculated according to the formulae below, and compared the calculation result with the inductor specification value to determine whether the inductor will be saturated (see Figure 6). This method is the most common and practical method available for engineers. Use the MPSmart simulation tool with the MP2145.
What to consider when choosing an inductor for a power supply?
Choosing an inductor for your power supply includes considering many parameters like DC resistance (DCR), rated current and saturation current. Among these parameters, saturation current is one of the most interesting.
Why does a magnetic field have a higher inductance?
When you have a material in a magnetic field that has higher permeability it intensifies the field. So a device that has a high permeability material will have higher inductance than the same device but without the material. This is a good property because it allows you to have higher valued components in less volume.
