A promising method for charging batteries of electric vehicles (EV) is inductive power transfer (IPT), also known as inductive charging. IPT, a convenient, safe, and aesthetic method of charging EVs, inductively transfers high-frequency AC power in the transmitting pad, or coil, to the receiving pad, or coil. However, the application of IPT entails several practical limitations. For example, misalignment of the coils and varied charging distance (air gap) between the coils change the magnetic coupling effect between the transmitting and receiving coils. As a result, system stability decreases because the electrical characteristics in different charging cycles vary. Previous research has rarely proposed an adaptive and effective method to solve the problems of varied coupling. Many EV models, however, exist on the market and more will be released in the future. A universal charger suitable for charging various models of EVs will have broad applications, especially in public charging areas. Therefore, we must design a universal inductive charger capable of providing stable charging voltage to various loads, even with influences by varied magnetic coupling. Also important is the design standard of on-board chargers used for universal inductive charging. The design schemes of the universal inductive charger and on-board chargers can be used as references for the future development of the entire EV inductive charging system.

Electric Vehicle (EV) has become an increasingly important topic in recent years due to energy and environmental concerns. Governments started to focus on remedies to the upcoming climate change threat and seek solutions through policies and regulations. The negative impact of carbon emissions along with pressure from governmental and social organizations force automotive manufacturers to shift to alternative energy sources. However, EV transition is a complex problem because its stakeholders are very diverse including governments, policy makers, EV manufacturers, and Non-Government Organizations (NGOs). Consequently, the barriers to EV adoption are not only consumer oriented, rather exist under many categories. The literature has yet to offer a comprehensive, quantified list of barriers to EV adoption. Although the enacted policies are known, the effectiveness of these policies in mitigating EV adoption is not known. The objective of this research is to assess policy alternatives for mitigation of EV adoption barriers by developing a comprehensive evaluation model. Barriers are grouped under Social, Technical, Environmental, Economic and Political (STEEP) perspectives that are perceived by decision makers as important for adoption process. The decision model of research links the perspectives to barriers, and policy alternatives. The research implements the hierarchical decision model (HDM) to construct a generalized policy assessment framework. Data for EV adoption barriers were collected from the abovementioned stakeholders. Experts' qualitative judgments were collected and quantified using the pair-wise comparison method. The final rankings and effectiveness of policy alternatives were calculated. This research's results showed that the most important perspective is Economic. The top three most important barriers to EV adoption were identified as Initial Cost, Battery Cost, and Entrenched Technology Resistance, respectively. The most effective policy in mitigating EV adoption barriers is R&D Incentives. The research also extended the policy effectiveness research with Policy Effectiveness Curves by reaching out to additional experts. These curves helped determine the effectiveness of each of the 6 policies at different implementation levels. Based on these results, 25 scenarios were applied by combinations of policies at different implementation levels to investigate how the effectiveness of policies can change compared to today's conditions.
