Tai Chi, a Chinese martial art developed based on the laws of nature, emphasises how 'to conquer the unyielding with the yielding.' The recent observation of star formation shows that stars result from the interaction between gravity, turbulence and magnetic fields. This interaction again follows the natural rules that inspired Tai Chi. For example, if self-gravity is the force that dominates, the molecular cloud will collapse isotropically, which compresses magnetic field lines. The density of the yielding field lines increases until magnetic pressure reaches the critical value to support the cloud against the gravitational force in directions perpendicular to the field lines (Lorentz force). Then gravity gives way to Lorentz force, accumulating gas only along the field lines till the gas density achieves the critical value to again compress the field lines. The Tai Chi goes on in a self similar way.

This book discusses topics related to power electronics, especially electromagnetic transient analysis and control of high-power electronics conversion. It focuses on the re-evaluation of power electronics, transient analysis and modeling, device-based system-safe operating area, and energy balance-based control methods, and presenting, for the first time, numerous experimental results for the transient process of various real-world converters. The book systematically presents both theoretical analysis and practical applications. The first chapter discusses the structure and attributes of power electronics systems, highlighting the analysis and synthesis, while the second chapter explores the transient process and modeling for power electronics systems. The transient features of power devices at switching-on/off, transient conversion circuit with stray parameters and device-based system-safe operating area are described in the subsequent three chapters. The book also examines the measurement of transient processes, electromagnetic pulses and their series, as well as high-performance, closed-loop control, and expounds the basic principles and method of the energy-balanced control strategy. Lastly, it introduces the applications of transient analysis of typical power electronics systems. The book is valuable as a textbook for college students, and as a reference resource for electrical engineers as well as anyone working in the field of high-power electronics system.

This book is dedicated to the analysis of the entrepreneurship in successful companies by presenting and comparing a series of case studies in the Asia-Pacific where many new companies have been growing successfully in the 21th century. In total, 5 cases in the manufacturing industry, 4 cases in the services industry, and 3 cases related to new business and social innovation are chosen from The mainland of China, Taiwan, Japan, Australia, Malaysia and Vietnam. Each case provides insight into the entrepreneur's aspiration, the processes of personal and business developments, the factors of success, and the inspirations drawn from the analysis. These cases are analyzed and compared from the viewpoints of entrepreneur's motivation, ability of foreseeing changes and opportunities in the future business environment, core resources and innovation, knowledge management and culture for the company, determination and ethos. These are critical factors in value creation for customers and the society, especially in the future business environment. Finally, commonalities and uniquenesses in entrepreneurship relevant to industry sectors and social-economic-cultural contexts are clarified and a typical entrepreneurship model in the Asia-Pacific is proposed.
