As one of the name parts of mechatronics, electronics is an integral component of mechatronic systems. They can be found in all areas of mechatronics, especially at the interfaces between the analog environment and digital information processing and in the control of mechatronic components such as electric motors.

After completing the module, students will be familiar with the main components, the structure and properties of analog electronic circuits and the design process (Electronic Design Automation, EDA). They will be familiar with various data sheets for individual components and integrated circuits. Students are able to calculate a given circuit or design and lay out a circuit according to given requirements.

The spectrum of circuits ranges from analog signal processing with rather low voltages and currents to the switching of larger loads, the control of DC motors and switching power supplies.

1. Fundamentals of electronics: Development process, description of circuits in the time and frequency domain, four poles

2. Components: Properties of passive components, diodes, thyristors, triac

3. Operational amplifiers: Basic circuits, properties, data sheets

4. Circuits with operational amplifiers: Analog controllers, comparators and A/D conversion, differential amplifiers, signal generators

5. Bipolar and field effect transistors: Basic function, structure, characteristics, properties, basic circuits, small signal behavior

6. The transistor as a switch: Switching simple loads, IGBT, switching AC voltages

7. Voltage and cuurent supply: Constant current sources, voltage regulators, rectifiers, switching power supplies

8. Control of electrical machines: Two-quadrant controller, four-quadrant controller, three-phase bridge circuit

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination

• Field work / Experimental work

The experimental work is carried out in the form of an internship. The experiments must be prepared and a report must be written.

Graded examination:

• Written examination: see applicable study regulations

Ungraded examination:

• Experimental work: 5 experiments, each lasting 90 minutes

Knowledge of electrical engineering fundamentals is required. This includes, in particular, direct and alternating current networks and the components used therein, such as resistors, capacitors and inductors.

In mathematics, the ability to work with complex numbers, solve linear equation systems and perform differential and integral calculus is required.

Students who have successfully completed this module will be able to recognise and calculate a given electronic circuit. They will be familiar with the components used.

Upon completion of the module, students will be able to design a suitable electronic circuit for a given task, select appropriate components and lay out the circuit.

They will also understand the importance of low power consumption in analogue circuits and the particular challenges of power electronics.

After completing this module, students will understand that there are differences between theoretical calculations and the actual properties of an analogue circuit. They will be able to assess the relevance of these differences and obtain the necessary information from component data sheets.

Students who have successfully completed this module will be able to design a simple analogue circuit and perform simulations, measurements and calculations.

Upon completion of the module, students will be able to process, present and discuss the results of selected analyses, simulations, measurements and calculations.
