Furthermore, it is demonstrated that the switch is scalable and can be cascaded.
Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters.
This switch is shown to have performance characteristics similar to the dedicated wavelength-convertible switch, with a cost closer to opto-electronic techniques.
These converters make use of several switches connected in a series, which allows using switches with reduced voltage ratings; these low voltage switches have lower conduction losses and can switch at higher frequency.
This improves efficiency, reduces the component count and size of the converters, and it is beneficial for circuit integration.

By comparing it with exiting main multilevel topologies, it is concluded that the proposed new topology is highly suitable for converters with a high number of levels.
It is found that two basic converters are, in general, required for implementing any of the possible configurations.
Since the switch voltage stress is minimized in the proposed circuit, it is allowed to use a device with a lower cost, higher efficiency, and higher availability.
Such characteristics are particularly important in high-power grid-connected converters used as an interface for renewable energy sources or smart grid applications.
Contrary to most of the converters that apply soft-switching techniques, the switches presented are not subjected to high switch voltage or current stresses and, consequently, present low conduction losses.
The proposed switch model exhibits a natural switching behavior, which is a valuable characteristic for the real-time simulation of power converters, thereby allowing individual treatment of switching devices irrespective of the converter topology.
It is suitable for interleaved and noninterleaved switched capacitor converters.
The proposed converters combine the advantages of simple topology, low bulk capacitor voltage, and no extra current stress across the switch.
It also compares favorably with other optical switch architectures, including path-independent insertion loss, Beneš, or switch-and-select networks, in terms of electrical interface.
In this scenario, it is very important for a switch to run at as low a speedup as possible.
The proposed converters give better performance when compared to the existing types.
Therefore, it can be a convenient approach for designing controllers to he applied to switched converters.
Due in part to the very high switch stresses in this interface, however, the cost appears to be too high to justify its use at this time.
