Book Description
(Cont.) From the mean power flow (charging) into the batteries per unit distance of travel and the power required by LED safety flashers, the effectiveness of the system at each speed and stopping frequency is examined. For cyclists traveling at average speeds of 10 mph or higher, the LED safety flashers can be powered continuously for stopping frequencies of 8 times per mile and semi-continuously (> 50% of the time) for stopping frequencies of at least 4 times per mile. As such, the system is determined to be potentially useful to urban commuter cyclists, who frequently perform braking operations at regularly spaced intersections and traffic signals, and who regularly travel by bicycle in low-light conditions (dawn or dusk), though usually less than 50% of the time.

Book Description
Design of Power Management Integrated Circuits Comprehensive resource on power management ICs affording new levels of functionality and applications with cost reduction in various fields Design of Power Management Integrated Circuits is a comprehensive reference for power management IC design, covering the circuit design of main power management circuits like linear and switched-mode voltage regulators, along with sub-circuits such as power switches, gate drivers and their supply, level shifters, the error amplifier, current sensing, and control loop design. Circuits for protection and diagnostics, as well as aspects of the physical design like lateral and vertical power delivery, pin-out, floor planning, grounding/supply guidelines, and packaging, are also addressed. A full chapter is dedicated to the design of integrated passives. The text illustrates the application of power management integrated circuits (PMIC) to growth areas like computing, the Internet of Things, mobility, and renewable energy. Includes numerous real-world examples, case studies, and exercises illustrating key design concepts and techniques. Offering a unique insight into this rapidly evolving technology through the author’s experience developing PMICs in both the industrial and academic environment, Design of Power Management Integrated Circuits includes information on: Capacitive, inductive and hybrid DC-DC converters and their essential circuit blocks, covering error amplifiers, comparators, and ramp generators Sensing, protection, and diagnostics, covering thermal protection, inductive loads and clamping structures, under-voltage, reference and power-on reset generation Integrated MOS, MOM and MIM capacitors, integrated inductors Control loop design and PWM generation ensuring stability and fast transient response; subharmonic oscillations in current mode control (analysis and circuit design for slope compensation) DC behavior and DC-related circuit design, covering power efficiency, line and load regulation, error amplifier, dropout, and power transistor sizing Commonly used level shifters (including sizing rules) and cascaded (tapered) driver sizing and optimization guidelines Optimizing the physical design considering packaging, floor planning, EMI, pinout, PCB design and thermal design Design of Power Management Integrated Circuits is an essential resource on the subject for circuit designers/IC designers, system engineers, and application engineers, along with advanced undergraduate students and graduate students in related programs of study.

Book Description
Handbook on Electric Vehicles Manufacturing (E- Car, Electric Bicycle, E- Scooter, E-Motorcycle, Electric Rickshaw, E- Bus, Electric Truck with Assembly Process, Machinery Equipments & Layout) An electric vehicle (EV) is one that is powered by an electric motor rather than an internal-combustion engine that burns a mixture of gasoline and gases to generate power. As a result, such a vehicle is being considered as a potential replacement for current-generation automobiles in order to solve issues such as:- a) Growing Pollution b) Global Warming, c) Natural Resource Depletion, and so on. Despite the fact that the concept of electric vehicles has been around for a long time, it has garnered a lot of attention in the last decade as a result of the rising carbon footprint and other environmental implications of gasoline-powered vehicles. The global electric vehicle market is expected to increase at a CAGR of 21.7 percent. Increased government investments in the development of electric vehicle charging stations and hydrogen fuelling stations, as well as buyer incentives, will provide chances for OEMs to increase their revenue stream and regional footprint. The EV market in Asia Pacific is expected to develop steadily due to increasing demand for low-cost, low-emission vehicles, whereas the market in North America and Europe is expected to rise quickly due to government initiatives and the growing high-performance passenger vehicle segment. India's flagship plan for boosting electric mobility is FAME, or Faster Adoption and Manufacturing of (Hybrid and) Electric Vehicles FAME Scheme has been authorized by the government, with 86 percent of overall budgetary support has been set aside for the Demand Incentive, which aims to increase demand for EVs throughout the country. This phase will support e-buses, e-3 wheelers, e-4 wheeler passenger cars and e-2 wheelers in order to build demand. The book covers a wide range of information related to the manufacture of electric vehicles. It includes E- Car, Electric Bicycle, E- Scooter, E-Motorcycle, Electric Rickshaw, E- Bus, Electric Truck with Assembly Process, contact information for machinery suppliers, Directory Section & Factory Layout. A detailed guide on the manufacturing and entrepreneurship of electric vehicles. This book serves as a one-stop shop for everything you need to know about the Electric Vehicle Manufacturing industry, which is rife with opportunities for startups, manufacturers, merchants, and entrepreneurs. This is the only book on the production of commercial electric vehicles. It's a veritable feast of how-to information, from concept through equipment acquisition.
