Basics of power electronics, power supplies, including electrochemical sources, rectifiers, stabilizers, the most commonly used types of motors, basics of power distribution, types of electrical systems and connecting appliances with a focus on medical use. Emphasis is placed primarily on the physical nature of the problem and its understanding. knowledge will be verified on practical examples and in the laboratory.


Knowledge of electrical engineering and electrical circuits. Due to individual measurements, it is necessary to know the procedures from the subject of electrical measurements.

Syllabus of lectures:

1. Introduction to the subject (content and conditions of credit and exam), characteristics of high-current electronics, basic schematic marks for drawing diagrams, power electronics - division of converters, description of function including basic characteristics, examples and practice in healthcare, power supplies - division, block diagrams , characteristics (D. Vrba).

2. Single and three-phase systems, dimensioning of conductors. Electrical devices - fuse devices and circuit breakers - principles and parameters, their connection (selectivity, contemporaneity) (D. Vrba).

3. Transformers - principle, equivalent circuit model, phasor diagrams, operating states, parameters, clock angle, transformer - single-phase, three-phase and autotransformer, isolating, isolating, use, requirements and applications in healthcare, requirements of the set of standards ČSN 60601-1 (D. Vrba).

4. Rectifiers and stabilizers (regulators) - single- and three-phase, single- and multi-pulse, applications in healthcare (D. Vrba).

5. Production and distribution of electricity (briefly, only an overview in the Czech Republic), types of distribution systems (TN, ie TN-C, TN-S, TN-C-S, TT, IT). Protection against electric shock - basic protection and fault protection (D. Vrba).
