Linear Non Linear Digital control for DC/DC Converters with fast transient response PARTE II
This article presents a digital control that improves the stability of the system, solves the problem of the limit cycle, shortens the recovery time and limits the overcoming of the rectified output voltage. The digital linear-nonlinear control function for DC / DC converters is described. The simulation model in the mixed environment of matlab-simulink / active -hdl is described. Preliminary results of the preliminary hardware test on a step-down-phase converter are presented and simulation and experimental results are also presented.
Analysis of driving cycles effects on power supply requirements of a fuel cell powered light-weight electric vehicle
In this paper, fuel cell powered lightweight vehicles are addressed. A MATLAB/Simulink simulation model including motor, electrical drive, the fuel cell and power electronics systems is implemented. The model is well suited to perform the driving cycle test, which reproduces the speed pattern of an electric vehicle through urban, rural or motorway routes. This paper aims at investigating the most suited driving cycle to design high performances hybrid power supply for electric vehicles in terms of cruising range, cost and size of the power supply equipment. For this purpose, a legislative and a real-world driving cycles are selected. Effects of driving cycles on the power system requirement…
