An algebraic model that describes the operation of binary Switched-Capacitor Converters (SCC) was developed and generalized to any radix case. The proposed approach reduces the power loss by increasing the number of target voltages. In the binary case, the flying capacitors are automatically kept charged to binary weighted voltages and consequently, the resolution of the possible target voltages is binary. The paper presents the underlining theory of the proposed SCC and two new control methods…
