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%.

“…De modo a destacar as vantagens e contribuições do conversor Boost-Forward, o mesmo foi comparado com outras topologias que têm por base os conversores Boost e Forward [16]- [19], conforme apresentado na Tabela II. Observa-se que o conversor Boost-Forward não apresenta maior ganho de tensão que os outros conversores, contudo, possui um menor número de componentes e menores esforços nos dispositivos semicondutores.…”

“…Contudo, o ganho de tensão do conversor Forward é restringido pela sua razão cíclica de operação, a qual é limitada em até 0,5 para permitir a desmagnetização do transformador (considerando que o enrolamento de desmagnetização possui o mesmo número de espiras do enrolamento primário). Deste modo, topologias integradas foram propostas na literatura de modo a superar estes inconvenientes [16]- [19]. Contudo, estas possuem um elevado número de componentes, o que se reflete em um aumento de complexidade e custo.…”

“…For that reason, perspective topological modification has been made. Most of the proposals are focused on the optimization of the voltage gain ratio in the pursuit of duty cycle improvement [1][2][3][4][5]. Many single-stage high voltage gain converters have been developed [6][7][8][9][10] with Figure 1 shows the dual interleaved DC-DC boost converter with magnetically coupled inductors.…”

High Gain Boost Interleaved Converters with Coupled Inductors and with Demagnetizing Circuits

This paper proposes double interleaved boost converters with high voltage gain and with magnetically coupled inductors, while a third coupled winding is used for magnetic flux reset of the core during converter operation. The topology of the proposal is simple, it does not require many additional components compared to standard interleaved topologies, and it improves the transfer characteristics, as well as system efficiency even for high power levels. The investigation of steady-state operation was undertaken. It was discovered that the proposed converter can be designed for a target application where very high voltage gain is required, while adjustment of voltage gain value can be done through duty-cycle variation or by the turns-ratio modification between individual coils. The 1 kW prototype was designed to test the theoretical analysis. The results demonstrate that the proposed converter achieves very high voltage gain (1:8), while for the designed prototype the peak efficiency reaches >96% even when two additional diodes and one winding were implemented within the converter's main circuit. The dependency of the output voltage stiffness on load change is minimal. Thus, the presented converter might be a proper solution for applications where tight constant DC-bus voltage is required (a DC-DC converter for inverters).
