Abstract :
This article presents a new Linear Voltage Stabilization System (LVSS) specially meant for 181;- hybrid vehicles using the Stop-Start function. The LVSS stabilizes the battery voltage mainly during the start-up of the ICE limiting the load current using parallels MOSFETs working in linear mode. The Energetic Macroscopic Representation (EMR) is used to model the system and to design its control system. The main advantages of the LVSS are the low price, small volume and the fact of avoiding EMC perturbation. The concept is validated testing the prototype in a real car.
