Switched-Capacitor Converters (SCC) suffer from a fundamental power loss deficiency which make their use in some applications prohibitive. The power loss is due to the inherent energy dissipation when SCC operate between or outside their output target voltages. This drawback was alleviated in this work by developing two new classes of SCC providing binaryâ€¦ (More)

A simple algebraic approach to synthesis Fibonacci Switched Capacitor Converters (SCC) was developed. The proposed approach reduces the power losses by increasing the number of target voltages. The synthesized Fibonacci SCC is compatible with the binary SCC and uses the same switch network. This feature is unique, since it provides the option to switchâ€¦ (More)

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, theâ€¦ (More)

A unified algebraic approach to the synthesis of generalized Fibonacci Switched Capacitor Converters (SCC) has been developed. The proposed approach reduces the power losses by increasing the number of target voltages. It is shown that the binary and Fibonacci SCC are private cases of the proposed approach. Furthermore, the proposed generalized SCC is builtâ€¦ (More)

A simple algebraic approach to synthesis Fibonacci Switched Capacitor Converters (SCC) is analyzed and the expected losses are estimated. The proposed approach reduces the power losses by increasing the number of target voltages. The synthesized Fibonacci SCC is compatible with the binary SCC and uses the same switch network. This feature is extremelyâ€¦ (More)

The paper proposes a new class of dual output step-up Fibonacci switched capacitor converters (SCC) and formal approach for its synthesis. The resolution of target voltages in the new SCC has been significantly increased in comparison with the previously developed single-output SCC, where the target voltages are spaced as 1/x. In the case of three flyingâ€¦ (More)

A new regulation technique based on duty cycle control of the average currents in the multi-phase switched capacitor converters (SCC) is proposed, analyzed, and verified experimentally for the No effective Charging (NC) case, also known as the fast switching limit (FSL). The regulation is accomplished by adjusting the value of the SCC equivalent resistor.â€¦ (More)

The paper proposes an algebraic approach to transient analysis of switched capacitor converters (SCCs). To this end, the SCC is considered as an analog computer that solves the system of linear equations by an iterative method. The result of each iteration represents a point in the step response, whereas the function between the points is reconstructed. Toâ€¦ (More)

The paper considers the shoot-through currents in two-phase switched capacitor converters (SCCs) as switching hazards. Despite the fact that the existing control circuits provide safe operation, there is no formal method to synthesize such circuits for multiphase SCCs. Besides that, the existing circuits are synchronous and therefore do not sustain largeâ€¦ (More)

A method for adiabatic charging of a capacitor by Switched Capacitor Converters (SCC) with multiple target voltages is presented, analyzed and verified experimentally. The SCC automatically changes the target voltages from low to high and back, thereby emulating voltage steps. This reduces the energy losses due to small voltage deviations between the SCCâ€¦ (More)
