This course reviews the various types of coil design for maximum coupling coefficient, including circular, rectangular, flux pipe, double D, and DDQ coils. Measurements of coil inductance will be discussed. Topics covered include: Coil layout structures; Field analysis and numerical analysis; Calculation of mutual and self inductance; Measurement of coupling coefficient; and Design for handling of misalignment.
This course will review other aspects of wireless chargers, such as safety issues, switching frequency band requirement, SAE WPT J2954 standard, object detection methods, communication methods between transmitter and receiver, some testing results of foreign object inserted between the transmitter and receiver are shown. Topics covered include: Human, animal and environment safety; Object detection; SAE J2954 standard for WPT; Wireless communication between the transmitter and receiver; Inductive coupling vs. capacitive coupling; In-motion charging vs. stationary charging and Other applications of WPT: medical, appliance, consumer electronics.
In this course, construction and operation of PM motor drives will be presented. PM machines are considered to have a higher torque density and ef?ciency than induction machines. Both surface-mounted PM (SPM) and interior PM (IPM) types are adopted for traction application. However, recent increase in the price of permanent magnets has led to an interesting competition between PM motors, Induction motors and reluctance motors. This module will present the fundamental concept of operation, types of PM motors and also discuss control strategies for the motor. Further, it will take a brief look at available permanent magnets, their properties and their impact on the performance on the machine. Topics covered include: Design and Construction of Permanent Magnet Machines: Motoring and Generation; Fundamentals of IPM and BLDC; Permanent magnets used in PM motors; Maximum torque per amp control strategy and Field Weakening concept.
It is important to understand how connected vehicles work and communicate. In this course, you will study the automotive system architecture and the secure vehicular cloud server platform. Upon completion, you will have a better outlook on the future of driving lessons, real-time coaching, smart driving, the conventional parking lot, and smart parking solutions.
