The purpose is to investigate the suitability of DBT as potential insulating material for high temperature applications, such as encapsulant in high temperature power electronics modules. Measurements were carried out using a special high temperature test cell, under nitrogen atmosphere. Sphere-sphere electrodes and voltage ramp were used. Results show some reduction of breakdown voltage at high temperature, down to 58.2% at 350°C. A similar effect is observed when pressure is reduced. This reduction occurs when the liquid approaches boiling conditions, hence facilitating the appearance of vapor bubbles.[/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]Boiling conditions,Electrical breakdown,Electrical characterization,High temperature power electronics,Nitrogen atmospheres,Pressure variations,Sphere-sphere electrodes,Wide temperature ranges[/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][/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]Indonesia Endowment Fund for Education (LPDP) is gratefully acknowledged for the financial support to the first author and ARKEMA for their support on technical discussion and providing the DBT sample.[/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/CEIDP.2018.8544791[/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]
