Linear Voltage Stabilization System for Stop & Start vehicles

This article presents a new Linear Voltage Stabilization System (LVSS) specially meant for μ-hybrid vehicles using the “Stop & Start” function. The LVSS stabilize the battery voltage mainly during the start-up of the Internal Combustion Engine (ICE) limiting the load current using parallels MOSFETs working in linear mode [1]. The mains advantages are its small volume, avoid of EMC perturbations and specially its low price allowing Stop & Start vehicles to be more accessible to the market. The concept is validated testing the prototype in a real car.
