Power Electronics and Motor Drives
Since the first appearance of motor drives, SEMIKRON has been committed to supplying solutions for every power range. Starting with the first insulated power module, the SEMIPACK rectifier module series more than 40 years ago, the MiniSKiiP in particular has revolutionised the motor drive design for low and medium power systems.
Today SEMIKRON offers the complete industrial standard power module portfolio that serves a power range of 0.2kW to several megawatts. The portfolio is completed with high power IPMs, power electronic stacks and a comprehensive product line of driver electronics that help to reduce development effort and time-to-market. The latest Generation 7 IGBTs of two different suppliers, optimized for motor drive applications, boost performance and power density of motor drive converters.

... integrated current measurement shunts. The integration of the current measurement into the power module replaces expensive and bulky current sensors (i.e. Hall sensors). This reduces size and cost of the motor drive system
Power electronics systems dominate the world market with broad applications, from cellphones to electric vehicles and home appliances. Advances in power electronics play a crucial role in battling climate issues and helping nations to achieve a more efficient and greener environment.
One essential branch of power electronics that impacts every aspect of our lives is electric drives. With the rapid emergence of power electronics and control techniques, more advanced electric motor drives are now replacing older motor drives to gain better performance, efficiency, and reliability.
The main objective of this Special Issue is to seek high-quality contributions that highlight emerging power converter topologies and address recent techniques in robust and reliable power electronics converters, motor control methods. The topics of interest include but are not limited to:
Enhancing its value, this fully updated collection presents research and global trends as published in the IEEE Transactions on Industrial Electronics Journal, one of the largest and most respected publications in the field. Power Electronics and Motor Drives facilitates a necessary shift from low-power electronics to the high-power varieties used to control electromechanical systems and other industrial applications.
Initially, the only electric loads encountered in an automobile were for lighting and the starter motor. Today, demands on performance, safety, emissions, comfort, convenience, entertainment, and communications have seen the working-in of seemingly innumerable advanced electronic devices. Consequently, vehicle electric systems require larger capacities and more complex configurations to deal with these demands. Covering applications in conventional, hybrid-electric, and electric vehicles, the Handbook of Automotive Power Electronics and Motor Drives provides a comprehensive reference for automotive electrical systems.This authoritative handbook features contributions from an outstanding international panel of experts from industry and academia, highlighting existing and emerging technologies. Divided into five parts, the Handbook of Automotive Power Electronics and Motor Drives offers an overview of automotive power systems, discusses semiconductor devices, sensors, and other components, explains different power electronic converters, examines electric machines and associated drives, and details various advanced electrical loads as well as battery technology for automobile applications.As we seek to answer the call for safer, more efficient, and lower-emission vehicles from regulators and consumer insistence on better performance, comfort, and entertainment, the technologies outlined in this book are vital for engineering advanced vehicles that will satisfy these criteria.
The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The different parts of an AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection.
The Power Electronics and Motor Drive (PEMD) Group is a newly found research group by Dr. Hang Gao at Washington State University, Vancouver from Spring 2021. PEMD group is concentrated in the research on topologies, modulations, and controls of high power converters in renewable energy and motor drive applications.
"Current measurement has many applications in power electronics and motor drives. Current measurement is used for control, protection, monitoring, and power management purposes. Parameters such as low cost, accuracy, high current measurement, isolation needs, broad frequency bandwidth, linearity and stability with temperature variations, high immunity to dv/dt, low realization effort, fast response time, and compatibility with integration process are required to ensure high performance of current sensors. Various current sensing techniques based on different physical effects such as Faraday's induction law, Ohm's law, Lorentz force law, magneto-resistance effect, and magnetic saturation are studied in this thesis. Review and examination of these current measurement methods are presented.
PSIM provides solutions to a variety of power conversion-related applications, from automotive to aerospace, electronics, energy, and electric utilities. PSIM empowers users in every stage of the product design process, from concept verification to rapid control prototyping and hardware implementation.
Power supplies are the backbone of the electrified world. Converter requirements, advancements in semiconductor devices, magnetics, topologies, and control techniques require dynamic, accurate, and purpose-built power electronics simulation tools.
Modular multi-level converters (MMCs) are becoming more important as the grid grows smarter and renewables play an ever more important role. Simulating them poses unique challenges for power electronics designers because of their diversity. Simple multi-level converters and MMCs can have very few switches while more complex systems can have hundreds. This means teams must carefully consider losses, efficiency, controllability, harmonics, and interactions with other local converters.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled.
Standardized motors provide convenient mechanical power for industrial use. The largest are used for ship propulsion, pipeline compression and pumped-storage applications with output exceeding 100 megawatts.
Applications include industrial fans, blowers and pumps, machine tools, household appliances, power tools, vehicles, and disk drives. Small motors may be found in electric watches. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.
Electric motors produce linear or rotary force (torque) intended to propel some external mechanism, such as a fan or an elevator. An electric motor is generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Magnetic solenoids are also transducers that convert electrical power to mechanical motion, but can produce motion over only a limited distance. 041b061a72
