Therefore, the goal of highest efficiency is met by selecting an induc-tor that provides sufficient inductance to smooth out the ripple current while simultaneously minimizing losses. The inductor must pass the current without saturating the core or over-heating the winding.
Key considerations in inductor selection include: Inductance—the rated value of the inductor and its impact on the ripple current in the buck converter. DC current rating—translated from the output current needs of the buck converter, the DC current rating is linked directly to the temperature rise of the inductor and its DC resistance (DCR).
In this topology, the energy storage inductor is charged from two different directions which generates output AC current . This topology with two additional switching devices compared to topologies with four switching devices makes the grounding of both the grid and PV modules. Fig. 12.
Inductor efficiency is highest when the combination of core and winding losses are the lowest. Therefore, the goal of highest efficiency is met by selecting an induc-tor that provides sufficient inductance to smooth out the ripple current while simultaneously minimizing losses.
The tool may also be used to graph the inductance vs current behavior to compare traditional hard-saturating inductors to soft saturation types. To select the highest eficiency inductor, the results can be first sorted by total loss. Multiple sorts allow selection by multiple parameters. Inductor loss is closely related to core size and wire size.
Inductor core saturation can often be observed directly in the converter current waveform where di/dt is inversely proportional to inductance. As inductance drops due to core saturation, the current slope increase rapidly. This can cause noise and damage to other components.
