“…Figure 8d,e is the output voltage of capacitors C 1 and C 2, which are 62.50 V. In Figure 8f voltage stress across the switch S is 62.50 V. Thus, the output voltage of the proposed converter is higher than voltage stress. Furthermore, a comparison of results demonstrates that voltage gain of the conventional quadratic converter is significantly less than the proposed converter, whereas voltage stress across the switch is equal to output voltages [11]. Figure 8g-i shows the current across the inductor L 1 , L 2, and L 3 .…”

An increase in demand for renewable energy resources, energy storage technologies, and electric vehicles requires high-power level DC-DC converters. The DC-DC converter that is suitable for high-power conversion applications (i.e., resonant, full-bridge or the dual-active bridge) requires magnetic transformer coupling between input and output stage. However, transformer design in these converters remains a challenging problem, with several non-linear scaling issues that need to be simultaneously optimized to reduce losses and maintain acceptable performance. In this paper, a new transformer-less high step-up boost converter with a charge pump capacitorand capacitor-inductor-diode CLD cell is proposed using dynamic modeling. The experimental and simulation results of the proposed converter are carried out in a laboratory and through Matlab Simulink, where 10 V is given as an input voltage, and at the output, 100 V achieved in the proposed converter. A comparative analysis of the proposed converter has also been done with a conventional quadratic converter that has similar parameters. The results suggest that the proposed converter can obtain high voltage gain without operating at the maximum duty cycle and is more efficient than the conventional converter.

“…The traditional boost converters are preferred for their simple structure and low cost; however, they usually produce high input current ripples. For high voltage gain, this converter needs to work at a high duty ratio cycle, which causes switching problems [9][10][11][12][13].…”

“…The cascaded boost converter requires a dual control strategy to control dual switch, whereas QBC requires only a single control strategy, since they have only one switch. QBC eliminates the requirement of the additional driver circuit and thus further enhances the output voltage by minimizing the losses [33]. Thus, QBC is used for many renewable energy applications.…”

This paper proposes an artificial neural network (ANN) based maximum power point tracking (MPPT) control strategy for wind energy conversion system (WECS) implemented with a DC/DC converter. The proposed topology utilizes a radial basis function network (RBFN) based neural network control strategy to extract the maximum available power from the wind velocity. The results are compared with a classical Perturb and Observe (P&O) method and Back propagation network (BPN) method. In order to achieve a high voltage rating, the system is implemented with a quadratic boost converter and the performance of the converter is validated with a boost and single ended primary inductance converter (SEPIC). The performance of the MPPT technique along with a DC/DC converter is demonstrated using MATLAB/Simulink.

“…With the rapid development of portable electronic devices, the requirements for power management systems are getting higher and higher. How to reduce the design complexity, reduce the cost, improve the conversion efficiency and speed up the transient response of the power supply system are the most basic and significant issues now [1,2,3,4,5]. As one of the power sources, DC-DC switching power supply is widely used in the modern electronic product market due to its high integration, high efficiency, small size and strong anti-interference ability [6,7].…”

An improved adaptive-on-time (IAOT) controlled current mode buck converter with RC-based current-sensing circuit and internal softstart property is presented in this paper. First, the inductor current is sensed by a resistor-capacitor (RC) network, which can fully sense the trend of inductor current with high accuracy. Second, an IAOT control circuit is used to realize the on-time of the power switch adaptively changing with the operation conditions. In addition, the overshoot (undershoot) voltages are reduced by making T ON adaptively shorter (longer) during the unloading (loading) transient due to the IAOT control. Third, soft start operation protects the circuit from large in-rush current during startup of the converter. Fourth, the proposed buck converter was implemented with standard 0.18-µm CMOS process. Simulation outcomes have shown an input voltage of 5 V, when the output voltage is ranging from 1.2 V to 3.6 V, with a maximum conversion efficiency of 98% (heavy loads) and 94% (light loads), making the buck converter quite useful in power management ICs.
