Abstract:
Nowadays, the development of technology cannot be separated from energy demands. An increasing energy requirement needed power electronic circuits to support systems that are producing a direct voltage or commonly called Direct Current (DC). A problem obtained is to convert the desired voltage level according to desired requirements. The development of power electronic circuits can be solving these problems by using a DC-DC converter topology. In general, DC-DC converters have several topologies such as buck converter, boost converter, buck-boost converter, and Cuk converter. In this research, an inverting buck-boost converter topology is designed and implemented to increasing and decreasing voltage. The aim of this research is converting the input DC voltage value to the constant output DC voltage value. A value of duty cycle configuration is depending switch on and switch off from MOSFET, which generated from Arduino Mega 2560. The results of the average output voltage value from t
he mathematical condition is 12 Volt; after that, from simulation condition is 12,05 Volt and then from implementation condition is 9,92 Volt. The results of the average ripple output voltage from the mathematical condition are 0,4%, after that from the simulation is 0,79% and then from implementation condition is 0,56%. The results of the average ripple value current from the mathematical condition are 6.54% and then from simulation condition is 6.94%. Finally, the buck-boost converter system that has been designed from this research has obtained an average value of power efficiency in the simulation conditions is 65.12% and then from implementation condition is 74,87%.
