“…According to this figure and in the range shown in it, the proposed converter switches have the lowest NPVS compared to the switches in the other converters for all values of n. Figure 7a shows the average NPVS of all semiconductor elements in each structure versus duty cycle for constant turn ratio. Regarding this figure, the average NPVS of the proposed converter is higher than that of the converter in [17] and it is lower than the average NPVS of other compared structures for D < 0.7. The average NPVS of the converter in [24] is lower than the average NPVS of the proposed converter for D > 0.7, but in this range, the conduction losses are high.…”

This paper proposes an interleaved coupled‐inductor high step‐up direct current (DC)–DC converter. This converter uses a coupled inductor (CI), a voltage multiplier (VM) integrated with a regenerative passive lossless clamp circuit to enhance the voltage conversion ratio. The interleaved structure is used as the front stage of the proposed converter to reduce the input current ripple. The proposed converter has benefits such as low voltage stress across semiconductor elements, high voltage gains, and continuous input current, which makes it suitable for applications such as renewable energy sources. In addition, to reduce the negative effects of leakage inductance and recover the energy stored in it, a diode‐capacitor clamp circuit is used. Moreover, a comprehensive analysis has been done on the details of the performance of the proposed converter in different operation modes. Also, its design, the voltage and current equations of all the elements, and efficiency analysis are obtained. In addition, a comprehensive comparison has been made with some similar converters. The experimental results of a prototype with 260 W 96.9% is presented to validate the performance of the proposed converter.

“…However, for fuzzy conditions, the logic algorithm to control the duty cycle can be divided into five variables comprising NB (Negative Big), NS (Negative Small), ZE (Zero), PS (Positive Small) and PB (Positive Big) [25][26][27][28]. The single-channel boost converter control uses the basic conditions voltage variable, current variable input and duty cycle output as shown in Figure 10.…”

Fixed-speed wind turbines for generating electricity are also important because they are clean energy and do not pollute the environment. Developing maximum wind energy tracking and increasing DC voltage to optimal values is also an important factor designers must consider so that the power from generators connected to wind turbines can function efficiently. Therefore, in this researcher paper proposed a single-channel dc/dc boost converter control, three forms of algorithms consisting of neural networks, fuzzy algorithms and PID algorithms. The purpose of bringing these algorithms controlled because they wanted to compare the response and voltage control performance of the single-channel DC/DC boost converter to be associated with a three-phase inverter that controls PWM signal modulation with space vector technique. However, the principles and methodologies in this article are presented to simulate the algorithmic response using the MATLAB/Simulink program and compare it with the prototype mechanism. A comparison of the response performance and voltage regulation of the single-channel DC/DC boost converter showed that the three algorithms have different advantages and disadvantages but can be used together to achieve high efficiency.
