Introduction Inductors and capacitors are a primary component in the dc- dc converter topology, which controls power from the computer to aircraft. DC-DC converters necessitate the need for energy storage components, particularly inductors. These components dwell in a huge area, and their usage is a most important chal- lenge in all power supply unit where small outline systems are required [1]. It is determined that L and C size depends on the switching frequency of the converter. The fall of size is a com- mon trend observed in the electronics business nowadays. The major design challenges for the power engineers are board size and efficiency of the converter. It is necessary to balance the cost, performance, and size of the converter for all the applica- tions. When switching frequency (100 kHz to 1 MHz) is higher, it faces many issues such as electromagnetic inference, skin- effect, proximity effect in the design of the converter, principally those related to the design of the magnetic components [2]. Therefore, a detailed analysis of these components is crucial for an optimized design [3]. There are many optimization tools available to obtain the optimized value to minimize the objec- tive function. In this work, we used the genetic algorithm to determine the optimized value [4]. Reliability analysis is done using MIL handbook [5]. The paper is organized as follows: Section 2 presents the pro- posed topology. Optimized switching frequency is obtained using the genetic algorithm, and it is shown in Section 3. Part 4 and 5 depict the material analysis of inductor and capacitor respectively. Reliability analysis of the proposed topology is presented in Sec- tion 6. Advantage of the proposed topology is presented in Sec- tion 7. Simulation results are discussed in Section 8. Finally, the paper is concluded in Section 9. 2. Voltage-lift based quadratic boost converter Voltage-lift cell is integrated with the quadratic boost converter to derive the proposed topology [6,7]. Fig. 1 gives the circuit dia- gram of the derived topology. It consists of three inductors Induc- tor (L 1 ,L 21 ,L 22 ), three capacitor (C 1 ,C 2 ,C O ) and five diodes (D 1 -D 5 ). It is a single switch converter. The integration of voltage-lift cell increases the voltage conversion ratio of the converter. 2.1. Voltage gain of the proposed topology The voltage conversion ratio can be acquired by applying volt- second balance principle on the inductor voltage equations during ON and OFF time of the switch in the converter. By utilizing the principle, we derive https://doi.org/10.1016/j.matpr.2020.02.660 2214-7853/Ó 2020 Elsevier Ltd. All rights reserved.
