“…As an innovation with respect to the state of the art, the proposed 48 V DC/DC converter avoids cumbersome transformers vs. inductor based converters [3] [4], and increases the working voltage and current levels vs. known switched-cap converters [5] [6], typically limited to low-power applications.…”

DC/DC applications in automotive market are expected to require new system specifications in next years. Because of the spreading of electrical cars, the power line at 48 V will be very common. Moreover, the converter chips and external passives are required to occupy less area. A DC/DC solution, meeting such requirements, is presented in this work. The switched capacitors architecture is intended to reduce external passive devices space occupation, whereas sustained electrical power is kept high. This paper discusses a preliminary version of the converter, with experimental results from measurements, and presents the final chip architecture, with some simulation result data.

“…It aims at controlling 28V up to 32V heavy duty alternators by rotor high current driver up to 5A in order to provide alternator output current to the battery and loads. It integrates on the same die a DC-DC converter to drive rotor coil, similar to the one described in [9], different I/O interfaces, a power management block and a small digital part that manage a serial communication with an external digital core, implemented on an FPGA. The FPGA solution has been chosen to increase the flexibility, like in [10].…”

Abstract-In this paper, a proposed methodology to identify the substrate coupling effects in smart power integrated circuits is presented. This methodology is based on a tool called AUTOMICS to extract substrate parasitic network. This network comprises diodes and resistors that are able to maintain the continuity of minority carrier concentration. The contribution of minority carriers in the substrate noise is significant in high-voltage and high temperature applications. The proposed methodology along with conventional latch-up problem identification for a test case automotive chip AUTOCHIP1 are presented. The time of the proposed methodology is significantly shorter than the conventional one. The proposed methodology could significantly shorten the time-to-market and ameliorate the robustness of the design.

“…Much research is going on to make the electronics and sensors in EVs more compact, rugged and cheaper-which in many cases are leading to advanced solid state devices that can achieve these goals with promises of cheaper products if they can be mass-produced. Some examples can be the works on gas sensors [197], smart LED drivers [198], smart drivers for automotive alternators [199], advanced gearboxes [200], and compact and smart power switches to weather harsh conditions [201]. The findings of [202][203][204][205][206][207][208] may prove helpful for studies regarding fail-proof on-board power supplies for EVs.…”

Electric vehicles (EV), including Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV), Plug-in Hybrid ElectricVehicle (PHEV), Fuel Cell Electric Vehicle (FCEV), are becoming more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace internal combustion engine (ICE) vehicles in the near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system could face huge instabilities with enough EV penetration, but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of the smart grid concept. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emissions produced by the transportation sector. However, there are some major obstacles for EVs to overcome before totally replacing ICE vehicles. This paper is focused on reviewing all the useful data available on EV configurations, battery energy sources, electrical machines, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector.
