Study of AC-DC converter
(BRAC University, 2018-10)
The modern electronic devices operate with low DC output voltage. The AC utility supply needs
to be converted and step down to a suitable DC voltage. During earlier days, the converters were huge in size and were expensive ...
Smart agricultural system for crop monitoring and soil analysis
(Brac University, 2022-12)
Agriculture is the base of the economy in Bangladesh, however, 90% of the farmers are not
familiar with modern-technological tools. That is the reason why we see very-little usage of
modern tools in farming in our country ...
Performance analysis of a MIMO optical wireless link with space time block code (STBC)
(BRAC University, 2014-08)
Performance analysis has been carried out for a space time block coded multiple input multiple output (MIMO) optical wireless link considering atmospheric turbulence. The diversity reception in the receiving has been carried ...
Acquisition and monitoring of multichannel ECG

Smart measurement of water quality parameters and monitoring fish health
(Brac University, 2021-05)
Every aspect of our daily lives is becoming more reliant on technology as it advances. Smart data measurement (smart data is information from which signals and designs have been extracted by using algorithms) is currently ...
Design of a single phase AC-AC converter
(BRAC University, 2012-04-12)
An AC-AC voltage controller is a converter which controls the voltage, current and average power delivered to an AC load from an AC source. They are used in practical circuits like light dimmer circuits, speed controls of ...
A detailed analysis on BUCK converter in different conduction mode
(BRAC University, 2018)
A DC-DC BUCK Converter is a basic type of switch mode power converter. It has variety of
application. It behaves differently in different conduction mode. In this thesis a buck converter is
designed first considering the ...
