Can a soft-switching converter be used in residential battery energy storage?

The prototype converter with a rated power of 300 W was assembled and tested considering future application to residential battery energy storages. The experimental test results prove feasibility of the soft-switching method in the proposed converter.

Are isolated converters better than dual active bridge converters?

Isolated converters, like the dual active bridge converter, achieve better conversion ratios by using winding turn ratios. However, they have a more complicated structures, high circulating currents that reduce efficiency, and high voltage stress on their output diodes.

What is a galvanically isolated DC-DC converter?

Galvanically isolated dc–dc converters with a current-fed (CF) port are a strong competitor for the conventional voltage-fed (VF) converters in low voltage and relatively high current applications, such as photovoltaic, fuel cell or BESS [ 5 - 8 ].

Is there a soft-switching bidirectional DC-DC converter with high voltage gain ratio?

A new interleaved coupled-inductor nonisolated soft-switching bidirectional DC–DC converter with high voltage gain ratio. IEEE Trans. Industr. Electron. 65 (7), 5529–5538 (2018) Lee, H.R., Park, J.H., Lee, K.B.: Optimal soft-switching scheme for bidirectional DC-DC converters with auxiliary circuit. J Power Electron. 18 (3), 681–693 (2018)

Can a bidirectional converter reduce voltage stress?

Notably, the converter in achieves zero-voltage switching (ZVS) for the switches and reduces the voltage stress. However, it suffers from a high number of switches. In this paper, a new bidirectional converter is proposed. This converter utilizes the switched inductor technique and incorporates only one magnetic component.

What are the advantages of using six switches on the secondary side?

Furthermore, employing six switches on the secondary side reduces the voltage stress of every switch by half of the output; the low on-resistance power switch is used, resulting in lower conduction loss. In addition, zero-voltage-switching of all power switches in the entire power range is realized to obtain high efficiency.
