20.500.12556/DKUM-60161 MOS-FET as a current sensor in power electronics converters This paper presents a current sensing principle appropriate for use in power electronics’ converters. This current measurement principle has been developed for metal oxide semiconductor field effect transistor (MOS-FET) and is based on UDS voltage measurement. In practice, shunt resistors and Hall effect sensors are usually used for these purposes, but the presented principle has many advantages. There is no need for additional circuit elements within high current paths, causing parasitic inductances and increased production complexity. The temperature dependence of MOS-FETs conductive resistance RDS−ON is considered in order to achieve the appropriate measurement accuracy. The “MOS-FET sensor” is also accompanied by a signal acquisition electronics circuit with an appropriate frequency bandwidth. The obtained analogue signal is therefore interposed to an A-D converter for further data acquisition. In order to achieve sufficient accuracy, a temperature compensation and appropriate approximation is used (RDS−ON = RDS−ON(Vj)). The MOS-FET sensor is calibrated according to a reference sensor based on the Hall-effect principle. The program algorithm is executed on 32-bit ARM M4 MCU, STM32F407. power electronics converters MOS-FET current measurement thermal model močnostna elektronika pretvorniki MOS-FET tekoče meritve true false true Angleški jezik Slovenski jezik Znanstveno delo 2016-06-09 03:15:17 2017-06-22 11:58:15 2022-06-22 03:06:06 2019-07-11 11:37:21 2015 0 0 str. 18061-18079 št. 8 Letn. 15 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1424-8220 681.5 10176278 18853910 10.3390/s150818061 1424-8220 URN:SI:UM:DK:H8AQLBFG Sensors_2015_Pajer_et_al._MOS-FET_as_a_Current_Sensor_in_Power_Electronics_Converters.pdf Sensors_2015_Pajer_et_al._MOS-FET_as_a_Current_Sensor_in_Power_Electronics_Converters.pdf 1 89E7A6DAB8F2C73BFC8A4C83661CAE30 a97384e643bb715b39ebfcdc7cc6d14a39c3eb21b3360e04324a9239eb30f503 4888d675-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112949 http://www.mdpi.com/1424-8220/15/8/18061/ 1 https://dk.um.si/Dokument.php?lang=slv&id=93976 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
