Generic and unified model of Switched Capacitor Converters

A Cascaded Switched-capacitor AC-AC Converter with a Ratio of 1/2<sup>n</sup>

“…As the single-stage circuit uses eight switches, the switching losses P sl8s due to parasitic capacitances of 8 MOSFETs are expressed by (13). This equation demonstrates that increasing the switching frequency of the AC-AC converter consequently increases the switching losses [6].…”

“…Previous studies on DC-DC converters have demonstrated that this SC cell can be represented by an equivalent resistance, as illustrated in Figure 6 (b), which is calculated using (1) for different duty cycle values and (2) for a duty cycle of 50% [11,12] (if the switching frequency become high enough, the value may change [13]). The model in Figure 6 …”

Generic average modeling and simulation of the static and dynamic behavior of Switched Capacitor Converters

“…The average behavior of SCC systems was analyzed in numerous earlier studies (e.g. [1][2][3][4][5][6][7][8][9][10]), in which the expressions of the voltage transfer ratios and the expected losses were derived.…”

“…The proposed simulation model is in fact a translation of the analytical results of [10] into average equivalent circuits. As such, the accuracy of the model is identical to the results of [10] and it is limited by the assumptions of its derivation (such that the subcircuits can be represented or approximated by a first order RC circuit).…”
