Dersin Tanımı

The course focuses on presenting the fundamental concepts on conversion, control and monitoring of electric energy using power semiconductor devices.

Methods for analyzing power electronic converters suitable for DC/DC and DC/AC electrical energy conversions including resonant converters/inverters are presented.

Additionally, principles for designing power electronic converters, including their power semiconductors and passive elements are established. Computer-aided analysis and simulations of the electrical performance of power electronic converters are also among the course objectives.

The application of power electronic converters in the fields of sustainable/renewable energy technologies such as wind and solar energy are described. Furthermore, industrial applications like SMPSs, UPSs and induction heating (resonant converters), as well as, application of power electronics for electric motor drives, transmission, distribution and control in the future power system, including micro and smart grids are described.

Details of the Course Description:
Characteristics of power electronic devices, switching characteristics of devices and review of power losses. Classes of power converters and their operations: DC/DC converters. Voltage and current source converters. Hard and soft-switching and resonant circuits. Power supplies (uninterruptible, switch-mode), power-factor-correction (PFC) circuits and designing the feedback controller, review of AC motor control theory (fundamentals of vector/field-oriented control), power electronics control principles, fundamentals of modulation methods (e.g. SPWM vs. SVPWM) for AC drives. Utility applications of power electronics, system design, implementation, control, and computer interfacing.
