Energy-Buffered Single-Phase Inverter Operating in the Fundamental Limit of Indirect Power

Optimization of DC-DC Power Supply Systems by Differential and Hybrid Power Processing

“…Due to the existence of 𝑃 𝑑𝑖𝑟 , the processed power by the components may be lower than the nominal output power 𝑃 𝑜𝑢𝑡 . The works in [37]- [41] have derived that the sum of the processed power has a lower limit for a given conversion gain, the "different power, 𝑃 𝑑𝑖𝑓𝑓 " as termed in [42], [43]. Literally, 𝑃 𝑑𝑖𝑓𝑓 describes "the best that can be done" [39].…”

“…These fundamental works from the 1960s have been used for circuit design in the literature [42], [43], [66], [92], [93], but the methodology has not drawn much attention. One reason is that it is not easy to know the 𝑃 𝑑𝑖𝑓𝑓 of a power architecture.…”

“…One reason is that it is not easy to know the 𝑃 𝑑𝑖𝑓𝑓 of a power architecture. This obstacle is solved by the VA area modeling proposed in [43], [94].…”

“…First, Chapter 2 reviews the historical timeline and SoA research on hybrid converters and power architectures. In Chapter 3 the methodology discussed in [37]- [43], [93], [95] is reviewed and re-organized to present a complete picture, thus, facilitating its usage in practical designs. New aspects to further complement the methodology, e.g., the hardware impact factor and several SoA converter structures (including the partial power converters) are also discussed.…”

“…Moore and D.H. Wolaver in [37]- [41], which is the basis of this thesis, is also a high-level evaluation method. It has been further elaborated and applied to practical circuit design in the literature, e.g., [42], [43], [94] and [92], [93], [95].…”
