“…It should be mentioned that some of these cells consist only of diodes and capacitors [see Fig. 11(b)-(d)] and hence are known in the literature as switched/diode capacitor VMCs [50], [51], [162]. Other VMCs have more components, such as an auxiliary switch [see Fig.…”

DC-DC converters with voltage boost capability are widely used in a large number of power conversion applications, from fraction-of-volt to tens of thousands of volts at power levels from milliwatts to megawatts. The literature has reported on various voltage-boosting techniques, in which fundamental energy storing elements (inductors and capacitors) and/or transformers in conjunction with switch(es) and diode(s) are utilized in the circuit. These techniques include switched capacitor (charge pump), voltage multiplier, switched inductor/voltage lift, magnetic coupling, and multistage/-level, and each has its own merits and demerits depending on application, in terms of cost, complexity, power density, reliability, and efficiency. To meet the growing demand for such applications, new power converter topologies that use the above voltage-boosting techniques, as well as some active and passive components, are continuously being proposed. The permutations and combinations of the various voltage-boosting techniques with additional components in a circuit allow for numerous new topologies and configurations, which are often confusing and difficult to follow. Therefore, to present a clear picture on the general law and framework of the development of next-generation step-up dc-dc converters, this paper aims to comprehensively review and classify various step-up dc-dc converters based on their characteristics and voltage-boosting techniques. In addition, the advantages and disadvantages of these voltage-boosting techniques and associated converters are discussed in detail. Finally, broad applications of dc-dc converters are presented and summarized with comparative study of different voltage-boosting techniques.

In this paper, a novel single-switch three-level (TL) boost converter for PWM dimming LED lighting is presented. Taking the system efficiency and output ripple into consideration, traditional two-level boost LED driver always employs additional active switch in order to deal with the dimming issue. However, the proposed TL boost converter has overcome the dimming control problem with only one switch by utilizing the "synchronous" PWM dimming approah, hence lower the system cost. Moreover, compared with the standard TL boost converter, the proposed topology not only maintains the advantage of using a lower voltage rating power switch that is rated half the output voltage, but also eliminates one active switch and its associated driving circuit. The operating principle and dimming scheme of the proposed TL boost converter is described in detail. A prototype of 11-W dimmable LED driving converter has been implemented to verify the design and analysis. The experimental result shows that singleswitch TL boost converter can regulate the LED current from zero to the rated 350mA with fast slew rate. A peak efficiency of 95% was achieved with 400kHz switching frequency.

“…But large switch voltage stress becomes one concern. [14,15] propose an effective topology that can achieve high voltage gains without high duty-cycle by cascading several voltage multiplier cells. Whereas, the high output voltage is achieved through lifting capacitor voltage step by step, making the capacitor voltage of the latter cell larger than that of the former cell.…”

This paper introduces the application of a switched-diode-capacitor voltage accumulator (SDCVA) on conventional boost converter. This study aims to obtain two different kinds of multi-input step-up converters with high voltage gains, low component stresses, low ripples, simple control and high conversion efficiencies: one is based on the parallel SDCVA and the other based on the serial SDCVA. The double-input step-up converter based on the parallel SDCVA and the double-input step-up converter based on the serial SDCVA are respectively taken as an example to do theoretical analysis, including operating principles and performance analysises when they work individually and simultaneously. The two proposed converters are implemented with a voltage closed-loop control at the switching frequency of 30kHz. Experimental results obtained from the implemented prototypes are provided to validate the feasibility and effectiveness of the proposed converters. Index Terms: SDCVA, multi-input, hign voltage gain, low component stress, simple control, high efficiency.
