9 / 14 page Board 4s SKYPER ® 32PRO R - Technical Explanations 9 2010-04-21 – Rev01 © by SEMIKRON Setting Soft Turn-Off RGoff_SC Designation Pattern Name Setting R160, R161 (parallel connected) MiniMELF RGoff_SC Factory setting: not equipped TOP R260, R261 (parallel connected) MiniMELF RGoff_SC Factory setting: not equipped BOT Temperature Signal The temperature sensor inside the SEMiX ® module is directly connected to contacting points T1 and T2. For details to the temperature sensor, see Modules Explanations SEMiX ®. Over Temperature Protection Circuit (OTP) The external error input SEC_TOP_ERR_IN on the secondary side (high potential) of the driver core is used for an over temperature protection circuit to place the gate driver into halt mode. Dimensioning OTP 1. Define an over temperature trip level according to the application. 2. Calculate the nominal ohmic resistance value of the temperature sensor at the defined trip level (see "Modules – Explanations - SEMiX ®" on SEMiX® product overview page at http://www.semikron.com). 3. The trip level on the adapter board is set with R172 by using the calculated resistance value. Factory setting R172: not equipped If no resistor is used, a failure signal is generated. Please note: If the contacting points T1 and T2 are used for adaptor of the temperature sensor, the Over Temperature Protection Ciruit must be disabled by taking out the resistors R175, R178 and R179. Safety Warnings: The contacting points T1 and T2 are not electrical isolated. Due to high voltage that may be present at the contacting points T1 and T2, some care must be taken in order to avoid accident. There is no cover or potential isolation that protect the high voltage sections / wires from accidental human contact. |
