SMV-2023-63: Measuring interferometric systems
Mikel, Břetislav
The contract research was focused on the development of multi-axis measuring systems using the most accurate method of measurement based on the principle of laser radiation interference. The basic reference is a laser source with a wavelength of 633 nm. Measuring systems are intended for devices requiring measurement accuracy in the order of nanometers.

Middle-level control of FB-MMC converter in Delta connection
Kokeš, Petr
Control of a modular multilevel converter (MMC) is technically far more complicated than control of a standard 2-level converter. It is not only because of a great number of series-connected cells. For a MMC converter we need to cope with another control level (mentioned here as the middle-level control), which means balancing of voltages among MMC branches and the control of currents circulating inside this converter. For the Delta connected MMC with full H–bridge (FH) cells a convenient method for voltage balancing among all three MMC branches has been analysed and the appropriate control structure has been designed. Then the functionality of this balancing method has been verified using computer simulations and also tested with two MMC physical models operating as active power filters on 400V and 6kV grids.
