Fundamental Concept of Power Electronics for Magnetic Researcher positioning is going to turn big when 80% of the electric energy comes to be used through a power electronics technology from now on in 10–20 years or so. Therefore, the power electronics technology may be said to be the minimum required knowledge to be learned by not only the electric person conce

Magnetic Property and Measurement Excited by PWM Inverterby an inverter for variable velocity operation. Because the electrical steel sheet is usually evaluated under an excitation of a linear amplifier which does not include time-harmonic components, it has a different magnetic property from the one which is excited by the inverter. So, the magnetic prop

Origin of Magnetism 90 Years of Misunderstandingabilization of the magnetic ground state) based on electron exchange energy. However, when his theory was invented, computer was not available to numerically solve many-body electron system, and he omitted the most important contribution from the nucleus–electron interaction (nucleus charge has a sh
