Switching Capacitors Transformerless Bidirectional DC-DC Converter
2020
This paper presents an innovative converter topology that better connects the needs of the battery pack and the electric motor towards the validation of an eco-sustainable electric mobility model. More in particular, the components of the proposed converter change their connection state during both the charging and discharging time of the battery, leading to a higher performance with respect to traditional step-down or step-up converters. The simulations carried out by means of the PLECS® environment have demonstrated the early feasibility of the proposed system.
A DC-DC power converter for PV module characterization
2014
In this paper, a standard-compliant electronic load setup for PV module curve detection which features high accuracy, low cost and components count is proposed. The proposed device is based on a DC-DC power converter in open-loop configuration. The proposed system is designed according to regulation constraints in order to achieve high performances in curve detection. Design criteria are discussed. The model is implemented in PSIM environment. Simulation based on data input of a commercial PV Conergy E215P module are carried out under several environmental conditions to show the accuracy of the proposed electronic load. Simulation results are reported.
Improving High Frequency Transformers behavior for DC-DC Converter Used in Electric Vehicles
2018
The paper presents a design procedure for high frequency transformer windings adopted in the DC-DC converter used in electric vehicles. The output of the design procedure is the integration of a 3D printed plastic case in the transformer windings, with the aim to maximize the output power. The proposal design procedure is entirely based on a finite element analysis approach and on a differential evolution algorithm used for the solution of the optimization problem.
Four Quadrant Switch Based Multiple-Input DC-DC Converter
2021
In this paper, a novel non-isolated multiple input dc-dc converter (MIC) is proposed. The MIC uses four-quadrant switches, only one inductor and capacitor. It is capable of bidirectional operation in non-inverting buck-boost configuration and can accommodate the simultaneous transfer of energy from more than one source of different voltage levels to the DC bus. This MIC is analysed for two inputs in this paper. As compared to existing MICs in literature, the proposed converter utilizes less number of inductors and requires only one switch to integrate any extra energy storage. Different operation modes of the proposed MIC are numerically verified and validated on a high-fidelity hardware-in…
