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.
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.
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.
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.
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.
Based on buck, boost or buck-boost topologies, which are well known in dc–dc converters, these inverters use dc inductors for energy storage or high-frequency transformers for both energy storage and electrical isolation as required for safety reasons. A buck-boost inverter topology with four power switching devices is shown in Fig. 11.
