Objectives

Programme

Part I.: Signal level electronics

Nonlinear circuits: Logarithmic and exponential amplifiers, rectifiers, limiters, piecewise linear circuits.

The phase-locked loops and their applications: Structure, linear small signal baseband model, different types of the PLL-s.

Analysis of the linear baseband model. Analog modulations: AM-DSB, AM-DSB/SC, AM-SSB, QAM, PM and FM. Modulators and demodulators.

Selective electronic circuits, filters: Specification, approximation, tolerance scheme, transformations. Active RC circuits, resonant filters (LRC circuits, ceramic filters, etc.).

 

Part 2: Power electronics

Power electronic semiconductor devices and modules: PN junction, Bipolar and Darlington Transistor, Thyristor, MOSFET, IGBT.

Grid commutation based single- and tree phase rectifiers, AC choppers. Calculation of active and reactice AC power. Power factor and harmonic emissions of rectifiers.

DC regulators: linear and switch-mode power supplies. Overcurrent protection.

DC-DC converters: buck, boost, buck-boost.

DC-AC converters: single phase half-bridge and full-bridge voltage source inverters with R, L, and RL loads.

Thermal problems of the electronic circuits, methods of heat removal. Conduction, convection, radiation. Thermal resistance and capacitance. Cooling methods, heat pipe. Thermal design of electronic devices with CFD. Heat sink of mobile equipment.

The course lays down the basics to understand the system level functions of more complex electronic systems including the underlining circuitry. It also presents the related calculation rules and design principles. The discussion of more complex electronic units is made possible by the ability to build upon previous knowledge from the Signals and Systems 1 and 2, Electronics 1, and Measurement Technology courses, thereby relating closer to the applications educated on major or specialization courses.   The skills in electronics obtained in the framework of this course (together with the course entitled Electronics 1) empower students with the necessary expertise to understand the courses of the study specialization blocks.

General rules
Requirements: During the term: For the signature: success on 2 written mid-term tests at a minimum pass (2) grade, presence on the practices as defined in the Code of Studies and Exams (CSE) successful presentation of the homework The homework is of circuit analysis type. Simulation software (e.g. PSPICE) can also be used to help solving the homework. Additional consultation is also provided for the homework if needed. The mid-term grade is calculated based on the weighted average of the two mid-term test and the homework results. Activity on the classes is also taken into account. During the exam period: none. Additional possibilities: For repeating the two mid-term tests, one repeat test occasion is provided during the term for each. One additional repeat occasion is provided during the repeat week, where one of the tests can be repeated. The total number of repeats taken cannot exceed three. At least one of the two mid-term tests needs to be successfully passed during the term. If the presentation of the homework is not successful during the term, then it can be repeated once during the repeat week.
