“…This is a technique of eliminating a particular current harmonic by tuning a low-pass filter to a specific frequency that uses low impedance such as 5 th multiple or 7 th multiple harmonics of the fundamental. High-pass filters on the other hand also consist of passive components with less impedance for harmonics at specific frequencies, thus filtering all harmonics present with higher frequencies [22]. These filters can be configured as the first order, second order, third order, and fourth-order high pass filters.…”

Solar energy is one of the most important renewable sources due to its advantages such as simple structure, convenient installation, diverse applications, and low maintenance costs. Low power generation is the main concern with solar panels, so the maximum transmission of this power is a prime priority. The design of boost converters with the ability to generate high voltage gain, efficient structure, and stable and low-cost control circuits is the first step after installing these panels. This study presents a simple and high-gain design of a step-up converter, which uses only one power switch. The significance of this issue is when it will be apparent to know that each switch needs a separate control circuit and complex systems require more control topologies. In comparison with the conventional converter, the gain of the proposed converter, with the use of two additional diodes, a capacitor, and an inductor, was five times greater than the gain of a classical converter with 80% of the duty cycle. The proposed converter can solve the narrow turn-off period problem for the power semiconductor components in order to achieve higher DC voltages that are possible at higher duty cycles in classical converters. Small signal analysis of the proposed converter is presented and a controller based on steady-space matrixes is presented. The reaction of the proposed controller is considerable since a deep mathematical analysis supports this controller. The principal operations of the proposed converter and the projected controller were analyzed mathematically and verified with the help of MATLAB/SIMULINK. Additionally, hardware implementation of the proposed converter was done on a laboratory-scale around 100 W.

“…Such problems can be solved by adding a switch to form a three-level boost converter [31]. Many other structures can also be integrated with quadratic converters like a capacitor-diode combination of the voltage multiplier or single/three-phase transformer windings [32]. There are different variations of boost converters, for instance, the quadratic boost zeta converter, quadratic tapped-boost converter 3 of 14 ZVS/ZCS quadratic converters, and quadratic converters based on non-cascading structures [33,34].…”

A New Efficient Step-Up Boost Converter with CLD Cell for Electric Vehicle and New Energy Systems

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 conventional boost converter, theoretically, has an infinite voltage gain at unity duty cycle; however, due to the parasitic resistance in the passive component, the maximum gain is much lower, and the maximum gain keeps decreasing as the load current increases [11,12].…”

A New Three-Level Flying-Capacitor Boost Converter with an Integrated LC2D Output Network for Fuel-Cell Vehicles: Analysis and Design

In this paper, a new three-level boost converter with continuous input current, common ground, reduced voltage stress on the power switches, and wide voltage gain range is proposed. The proposed converter is composed of a three-level flying-capacitor switching cell and an integrated LC2D output network. The LC2D output network enhances the voltage gain of the converter and reduces the voltage stress on the power switches. The proposed converter is a good candidate to interface fuel cells to the dc-link bus of the three-phase inverter of an electric vehicle (EV). A full steady-state analysis of the proposed converter in the continuous conduction mode (CCM) is given in this paper. A 1.2 kW scaled-down laboratory setup was built using gallium nitride (GaN) transistors and silicon carbide (SiC) diodes to verify the feasibility of the proposed converter.
