Molding and simulation of GaN step-up power switched capacitor converter

A Performance of the Soft-Charging Operation in Series of Step-Up Power Switched-Capacitor Converters

“…For instance, providing a higher voltage gain is unlikely to be achieved with SC converters. Furthermore, the SC converters cannot normalize the output voltage in a lossless approach due to the R ds_on resistors [5][6][7][8]. The proposed step-up PSC converter has demonstrated a higher gain voltage at a smaller number of elements compared to other SC topologies.…”

“…The PSC converter has a gain voltage V out = 2 n V in where n is the number of stages. Each added stage requires two additional capacitors and four more switches [7]. Unlike the other SC converters' topologies, the number of operation modes increase with the number of levels.…”

“…In this paper, the complete soft-charging operation has been applied to the proposed PSC converter in [7]. A control diagram has been proposed to achieve a complete soft-charging in a 1-to-4 PSC converter.…”

“…The result and discussion come in Section 5 before the conclusion. Figure 1 shows the topology of the 1-to-4 PSC converter and its control signals [7]. The control diagram in Figure 2a shows how four modes of operation are possible.…”

Soft-Charging Effects on a High Gain DC-to-DC Step-up Converter with PSC Voltage Multipliers

“…The new DC-to-DC converter is known as a Multilevel Boost Converter (MBC). Adding more output multipliers and keeping the main converter part (primary side) is the main aspect of the MBC converter [5][6][7][8][9][10][11][12][13]. The MBC increases the regulated output voltage by adding voltage cells, which are basically switched capacitors cells, but have drawbacks, such as the failure to produce the actual output voltage at higher duty cycles [14].…”
