The basic of US NDTsystem consists of High Voltage (HV) pulse generator, an ultrasonic transducer, high speed ADC and digital signal processing. To support education and training for engineering student for US NDT, affordable programmable HV pulse generator is designed and implemented. The pulse generator consists of DC-DC boost converter, programmable pulse width and duty cycle period using microcontroller and switching circuit. First, LTSpice is used for design and evaluation of electronic circuit pulse generator. Then, for testing the implemented system, HV pulse generator is performed. The pulse has an average output voltage around 178.08 V, rise time 108.33 ns, and decay time 3200 ns could be generated for 4 MHz US transducer. In the experiment test, the NDT using our proposed HV pulse generator could be used as NDT simulator for modelling of railway defects.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]DC-DC boost converters,Design and evaluations,Education and training,Experiment tests,High voltage pulse,High-voltage pulse generator,Non-destructive test,Ultrasound waves[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]non-destructive tests,pulse generator,simulator,ultrasonic[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is funded by the research grant from Ministry of Research, Technology and Higher Education (Indonesia) fiscal year 2018 and partly supported by USAID through Sustainable Higher Education Research Alliances (SHERA) Program – Centre for Collaborative (CCR) National Center for Sustainable Transportation Technology (NCSTT).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICA.2019.8916699[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
