“…In this paper, the NHSDCs are checked and the usage of SC, SI and SCI cells are identified in Table V, where the SC-, SI-and SCI-based converters with the highest and the lowest ISGC, ISGW and ISGS are also presented in Table III. According to Table V, most of the converters use these switching techniques where some topologies like [51,77,78,80,101,115,160] employ two techniques simultaneously. The results of Table I and Table V express that there is not a meaningful correlation between using two techniques, and ISGC, ISGW and ISGS metrics.…”

“…Hence, some approaches have been introduced in literature to alleviate or eliminate the aforementioned obstacles, and coping with them can be considered as a valuable criterion which affects the converter power loss, components stresses, cooling system size and cost. Among these approaches, the followings are the most applicable: ZCS in the turn-off transition [130,133,141,142,145,148,168,208,223], smooth turn-off due to inductive current [171,235], placement of a coupled inductor leakage inductance in series with diodes [1,77,119,120,121,122,130,131,132,147,222], usage of resonant or quasi resonant tanks [11,117,128,201], control-base solutions like operation in low duty cycles [44,115,134], employment of SiC diodes [212] (Note that, SiC diodes have higher forward voltage drop. ), and capability of using fast recovery diodes due to low voltage stress across diodes [118,123,137,173].…”

Due to the extensive role of non-isolated high step-up DC-DC converters (NHSDC)s in industrial applications and academic research, many of these pulse width modulation converters have been presented in recent years. For each of these NHSDCs, some claims are introduced to verify its capabilities and features, which has been investigated in some review papers with different frameworks. Dissimilar to previous review papers, which have focused on the classification and derivation of voltage boosting techniques, this paper aims to evaluate the converters from various topological and operational points of view, and determine the superiority of each technique and converter according to applications. Some of these metrics are voltage gain, stresses, ripple, cost, power density, weight, size, control complexity and components count which lead to a comprehensive comparative study. Then, as the main purpose of this paper, effectiveness of these metrics is assessed to show how well they can lead us to the fair comparison results. Moreover, some new figures of merit are proposed in this paper to provide a helpful guideline in power electronic converters comparison studies. Finally, the feasibility discussion of single-and multi-objective figures of merit is followed by general practical conclusion and outlook about the NHSDC structures.

“…On the other hand, it aids the advanced controllers, functions of duty cycles, to achieve more ambitious control goals because energy storage elements have been selected optimally. So, the proposed approach offers opportunities to enrich the family of parameter design methods [12][13][14][15][16][17][18][19][20][21][22][23][24][25] and empower the family of the control designs [31][32][33][34].…”

“…It was reported that an inductor core bias technique (ICBT) exhibited some smaller current ripple than the traditional inductance-neutral approach did [21]. Other methods were also proposed to reduce the output ripple of the converter [22][23][24][25]. Unfortunately, their transient responses are always unsatisfactory.…”

DC/DC converters are ubiquitous in renewable energies such as photovoltaic power systems. A novel and general approach is proposed that consists of three matching principles, which enables one to assign a best set of energy storage elements to a DC/DC converter to meet both desirable transients and small ripples, facilitating the design of a controlled DC/DC system. First, the principle of specification matching introduces a 'virtual' lower order model to meet the prescribed specifications. Second, the rule of order matching augments the 'virtual' model to a higher order, the same as that of the actual DC/DC circuit if necessary. Third, the principle of parameter matching helps derive desirable element parameters through solving an optimization nonlinear function with constraints. These principles are realized through a specific design method for boost DC/DC converters of a photovoltaic power system. Given some specifications, a numerical optimal design is executed to verify the effectiveness of the specific design tool as well as the proposed theory. A photovoltaic power system with the designed boost DC/DC converter is implemented in both the simulated environment and the physical environment.The experimental results show that both transient responses and steady state responses (or ripples) meet the given specifications. The proposed theory can either work alone in simple designs or assist in advanced control designs for a better performance.

Efforts to produce products in accordance with consumer needs, companies are required to produce quality products. Commitment to product quality will have a positive impact and win the competition for companies, especially in the food sector. For that, it is necessary to standardize the quality management system that is globally recognized. Hazard Analysis Critical Method (HACCPM) is a method to ensure food safety by obtaining HACCPM certification from the food organization used by PT. TCI Garut is a guarantee of food safety. The HACCPM method can identify key points in the production process, and it can help reduce the number of defective products produced. The results of applying the HACCPM method, PT. TCI Garut obtained HACCPM certification to ensure the food safety of its products, and succeeded in reducing the number of defective products from an average of 2.21% before HACCPM application to 0.91% after HACCPM application. From the results of HACCPM application, these important points are caused by the danger of pollution and the danger of additives that can endanger the health of consumers.
