This paper proposes a novel high-efficiency high-step-up interleaved converter with a voltage multiplier, which is suitable for electric vehicle power management applications. The proposed interleaved converter is capable of achieving high step-up conversion by employing a voltage-multiplier circuit. The proposed converter lowers the input-current ripple, which can extend the input source's lifetime, and reduces the voltage stress on the main switches. Hence, large voltage spikes across the main switches are alleviated and the efficiency is improved. Finally, a prototype circuit with an input voltage of 24 V, an output voltage of 380 V, and an output rated power of 1 kW is implemented and tested to demonstrate the functionality of the proposed converter. Moreover, satisfying experimental results are obtained and discussed in this paper. The measured full-load efficiency is 95.2%, and the highest measured efficiency of the proposed converter is 96.3%.

Abstract. This paper presents the concept of topologies and investigation results of switched-capacitor voltage multipliers designed for application in high power systems. The analyzed family of multilevel converters includes established topologies as well as novel concepts. The application of thyristors as well as the invention of novel concepts of multiplier topologies and appropriate control make it possible to achieve high efficiency, high voltage gain, reliable and simple DC-DC converters for high power systems. Based on analytical models of the SCVMs, the paper presents a discussion of the selection of components and the efficiency of the converters as a function of converted power as well as the voltage range on the input and the output side. The results are supported by computer simulations and demonstrative experimental tests. The SC converters operate using the principle of charge pumps and usually contain a large number of switches. However, high efficiency can be achieved in the SC converters by the application of resonant operation [4,15]. The SC converters can also be designed in an efficient way thanks to an appropriate selection of passive and active components [4,16]. The selection of the parameters of the passive components for an SCVM is a complex process and and it should be done considering the switch technology, power and required efficiency, which is demonstrated in [16].The SCVM topology is suitable for the application of thyristors as active switches [3,4,15]. Furthermore, the ability of bidirectional voltage blocking makes it possible to further optimize the SCVMs, as presented in [4,26,27], where the reduction of the number of switches is demonstrated in the topology called RSCVM. The application of thyristors creates possibilities for DC-DC conversion in resonant mode topology at high power, voltages and currents, owing to extremely high parameters of the thyristors. The resonant-mode operation is advantageous, because it makes turning-off the switches possible and assures zero current switching (ZCS) [4]. This paper, in Section 2, presents an analysis of the thyristor-based SCVM related to feasibility of the converter for high power application (Fig. 1a). The analytical results reach 500 kilowatts power, which makes it possible to demonstrate, in figures, the efficiency, range of currents as well as the value of LC parameters. Next, in Section 3, the thyristor-based topologies suitable for high power operation are presented (Figs. 1b, 1c, 1d). The evolution of the SCVM, presented in [4] is also

For grid-connected power system based on photovoltaic (PV) source and fuel cells, high step-up and high-efficiency DC-DC converters are needed, due to the bus voltage of the grid-connected inverter is much higher than the output voltage of PV and fuel cells. In this paper, a novel high step-up converter is proposed. An auxiliary capacitor is introduced into the boost converter, which serves as a voltage source. It is in series with the input voltage source with the same voltage polarities. Thus, the input voltage is increased equivalently and the voltage gain is increased accordingly. To reduce the voltage stresses of the switch and the diode, multiple output capacitors are introduced. The voltage of each output capacitor is degraded leading to the reduced voltage stress. To replenish energy for the multiple output capacitors, a coupled inductor is adopted. Based on this, high step-up converter adopting auxiliary capacitor and coupled inductor is derived. The operating principles and voltage gain of the proposed converters are analyzed in this paper. In the end, experiment results are given to verify the theoretical analysis.
