“…Hence, the comparison of different converter voltage gain concerning the variation in duty ratio is shown in Figure 15. From the plot, it is observed that the ASC‐QBC‐II converter has superior performance to all other converters, and ASC‐QBC‐I voltage gain is slightly less compared to the converters in Jalilzadeh et al 26 and Khan et al 33 The voltage gains of converters in previous studies 23‐24,27,28‐31 are far less than with other converters. However, if we consider voltage gain per component count then ASC‐QBC‐ I, II performance is superior to all other converters.…”

This paper presents active switched capacitor integrated ultra-voltage gain quadratic boost converters (ASC-QBC). The step-up conversion ratio provided by quadratic boost converter is not ample to meet the renewable microsource applications. The active switched capacitor integrated quadratic boost converter is a propitious alternate to acquire high voltage conversion ratios. A simple diode-capacitor voltage lift arrangement is used in one of the introduced converters, thereby further enhancing the voltage gain and also reducing the input current ripple to a greater extent. The voltage stress on semiconductor devices is greatly alleviated with the aid of diode-capacitor voltage lift arrangement. The input current ripple aspects with green energy sources along with control feasibility of the proposed converters against input voltage and load perturbations are experimentally demonstrated for a power rating of 100 W.The theoretical analysis and performance indices of proposed converters are validated with a fabricated laboratory prototype.

“…The comparison covers over 26 articles, all of which showcase different converter designs and their characteristics. Several research papers, such as [58][59][60][61][62][63], have been devoted mainly to the search for higher efficiency levels, between 94% and 95.3%, attained by applying sophisticated control techniques and complex circuit modifications. Among these efforts, [58] is noteworthy because it emphasizes the improvement of system stability using soft-switching methods, while [61] focuses on reducing copper losses to improve overall performance.…”

Conventional DC-DC boost converters have played a vital role in electric vehicle (EVs) powertrains by enabling the necessary voltage to increase to meet the needs of electric motors. However, recent developments in high-gain converters have introduced new possibilities with enhanced voltage amplification capabilities and efficiency. This study discusses and evaluates the state-of-the-art high-gain DC-DC converters for EV applications based on the Quadratic Boost Converter (QBC). Research into innovative topologies has increased in response to the increasing demand for efficient and high-performance power electronic converters in the rapidly expanding EV industry. Due to its ability to provide more significant voltage gains than conventional boost converters, the QBC has become a viable option for meeting the unique requirements of EV power systems. This survey focuses on the efficiency, power density, and overall performance parameters of QBC-based high-gain converters. The literature review provides a foundation for comprehending power electronics converters’ trends, challenges, and opportunities. The acquired knowledge can enhance the design and optimization of high-gain converters based on the QBC, thereby fostering more sustainable and efficient power systems for the expanding electric mobility industry. In the future, the report suggests that investigating new high-gain converter design methodologies will reduce component stress and enhance the intact system efficiency.

In this article, a transformer rail‐tapped buck‐boost converter (TRT‐BBC) with minor loss of power transfer from a photovoltaic solar panel to a lead‐acid battery for battery charging systems is designed. The TRT‐BBC has been utilized to inter‐match the PV direct power to the battery. The 24‐V lead acid battery bank with a storage energy of approximately 168 Wh is designed. The photovoltaic solar panel of 200 W maximum power is used for the whole system operation. The proposed TRT‐BBC topology solves the conventional buck‐boost converter inverted output problem with apex conversion efficiencies of 93.25% and 91.97% for continuous current mode (CCM) and discontinuous current mode (DCM) respectively at standard test conditions (STC) and full load conditions. The whole system can operate either in DCM or CCM according to the needs at a switching frequency of 100 kHz and the maximum power point tracking (MPPT) with proportional integration (PI) based constant voltage‐constant current (CV‐CC) feedback control loop used to monitor the switching duty cycle of the TRT‐BBC.
