| Summary: | To improve the nation's competitiveness, universities are required to keep
up with the current technologies in the world. However at the same time it is not
uncommon for universities and colleges to face a real challenges such as limited
funding, limited lab space and limited laboratory equipment. In power electronics
laboratory the problem with limitations in variety and numbers of the experiment
equipment the is partly because of the reliance on the completely-build unit that
has to be imported directly. Meanwhile, Internationally, power electronics has
undergone such evolution and revolution with the application of wireless
technology to monitor and control each of the power modules that are connected
in the network, such as what happens in smart grid.
The study begins with a general review of how to find equipments and
materials that are relatively easy to obtain locally. A review carried out including
to find softwares that can legally be used freely without paying any license fee
(such as GNU/Linux). The control system was first built using the Arduino Uno
embedded system. After control setting and appropriate communication algorithm
was obtained the research continued with the development of a system based on
the less expensive AVR ATtiny2313. XBee 802.15.4 OEM module was added as a
replacement for wired serial communication.
This study has been able to realize a practical platform that can be used in
power electronics laboratory using latest wireless technology that widely
available. Research has managed to get the basic configuration of a device that
can be easily realized by the students with the components that are relatively easy
to obtain locally. From the test results for PWM at 100 kHz switching frequency it
was shown the highest efficiency that can be achieved was 87.764%.
