A Buck-Boost inductor has to handle all the energy coming toward it — 50 μJ as per Figure 5.4, corresponding to 50 W at a switching frequency of 1 MHz. Note: To be more precise for the general case of η≤1: the power converter has to handle P IN /f if we use the conservative model in Figure 5.1, but only P O /f if we use the optimistic model.
While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well. See Linear Technology’s Application Note 77 for complete details.
In 22, a switched inductor technique is utilized to construct a high step-up boost converter with fewer components and a simple structure, but the voltage gain is significantly reduced at low voltage inputs with low efficiency due to the hard-switching work condition.
The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor.
The output ripple is reduced in a similar fashion. While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well.
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.
