Özet

High step-up DC-DC converters are used in many industrial applications Especially, renewable energy systems that have a low output voltage and high output current need DC-DC converters with high voltage gain to meet the requirements of the grid-connected systems for a high output voltage. This study is aimed to design an implementation of hardware of the high step-up DC-DC converter’s measurement board prototype for digital signal processing (DSP) TMS320F28335 development kits. The vital parameter to detect for high step-up application systems is a sampling output voltage. This sample of output voltage is produced by using the voltage transducer (LV 25-P) with hall effect sensor in this research. A signal conditioning circuit includes an operational amplifier featuring unity gain buffer for the protection ADC of the DSP and a low pass filter circuit. Therefore, the requirements of the ADC of EZDSP TMS320F28335 development kit can be met by using this voltage transducer sensor and the signal conditioning circuit
