Board 1 SKYPERTM 32PRO - Technical Explanations
Disclaimer In accordance with SEMIKRON's quality procedures, we hereby notify you that the Evaluation Board 1 SKYPERTM 32PRO should be considered as evaluation products only. Evaluation products are experimental products and are therefore only intended for device evaluation. SEMIKRON does not represent or guarantee that a final version will be made available after device evaluation. Evaluation products are subject to the change service. Although evaluation products have been manufactured using processes and procedures representative of final production, they have not been subjected to all of our normal quality audits and controls. Additionally, neither the product nor the manufacturing processes may have passed our internal qualification procedures. IMPORTANT: The evaluation boards are supplied without warranty of any kind, expressed, implied of statutory, including but not limited to, any implied warranty of merchantability of fitness for a particular purpose. Credit or replacement for evaluation products that fail to function will not be given nor will a failure analysis be performed. There is no entitlement to technical support for evaluation products. Claims for damages and reimbursement of expenses on the part of the undersigned customer shall be excluded, regardless of the legal cause, especially claims in contract and in tort. The liability exclusions shall not apply in cases of liability independent of the question of blame or negligence, especially claims under the German Product Liability Act in cases of wilful intent, gross negligence, or injury to life, limb or health and on account of a breach of major contractual obligations. Compensation for failure to comply with major contractual obligations shall be limited, however, to typical, foreseeable damages, unless wilful intent or gross negligence applies, or on account of liability for injury to life, limb or health. Any change in the burden of proof to the detriment of the undersigned customer shall not be associated with the aforesaid rulings FOR SAFETY REASONS THE CUSTOMER IS NOT ALLOWED TO SELL EVALUATION PRODUCTS TO ANY END CUSTOMER OR ANY OTHER THIRD PARTY. If the customer fails not to sell the evaluation products to any end customer or any other third party, then the customer shall indemnify SEMIKRON against all claims by the concerned end customer or third party in respect of any loss, damage or injury arising from the aforesaid reason.

Board 1 SKYPERTM 32PRO - Technical Explanations
Please note: All values in this technical explanation are typical values. Typical values are the average values expected in large quantities and are provided for information purposes only. These values can and do vary in different applications. All operating parameters should be validated by user's technical experts for each application.
Application and Handling Instructions Please provide for static discharge protection during handling. As long as the hybrid driver is not completely assembled, the input terminals have to be short-circuited. Persons working with devices have to wear a grounded bracelet. Any synthetic floor coverings must not be statically chargeable. Even during transportation the input terminals have to be short-circuited using, for example, conductive rubber. Worktables have to be grounded. The same safety requirements apply to MOSFET- and IGBT-modules. Any parasitic inductances within the DC-link have to be minimised. Over-voltages may be absorbed by C- or RCD-snubber networks between main terminals for PLUS and MINUS of the power module. When first operating a newly developed circuit, SEMIKRON recommends to apply low collector voltage and load current in the beginning and to increase these values gradually, observing the turn-off behaviour of the free-wheeling diode and the turn-off voltage spikes generated across the IGBT. An oscillographic control will be necessary. Additionally, the case temperature of the module has to be monitored. When the circuit works correctly under rated operation conditions, short-circuit testing may be done, starting again with low collector voltage. It is important to feed any errors back to the control circuit and to switch off the device immediately in failure events. Repeated turn-on of the IGBT into a short circuit with a high frequency may destroy the device. The inputs of the hybrid driver are sensitive to over-voltage. Voltages higher than VS +0,3V or below -0,3V may destroy these inputs. Therefore, control signal over-voltages exceeding the above values have to be avoided. The connecting leads between hybrid driver and the power module should be as short as possible (max. 20cm), the driver leads should be twisted.
Further application support Latest information is available at http://www.semikron.com. For design support please read the SEMIKRON Application Manual Power Modules available at http://www.semikron.com. General Description The Board 1 SKYPERTM 32PRO is an evaluation board for the IGBT module e.g. SEMITRANSTM, SEMiX (solder pin version). The board can be customized allowing adaptation and optimization to the used IGBT module. The switching characteristic of the IGBT can be influenced through user settings, e.g. changing turn-on and turnoff speed by variation of RGon and RGoff. Furthermore, it is possible to adjust the monitoring level and blanking time for the DSCP, soft turn-off behaviour as well as an over temperature trip level by using the temperature sensor (R) integrated in SEMiX modules (see Technical Explanations SKYPERTM 32PRO).

Board 1 SKYPERTM 32PRO - Technical Explanations
Signal IF_CMN_nHALT The Halt Logic Signals PRIM_HALT_IN and PRIM_HALT_OUT of the driver core are coupled to one bidirectional signal (IF_CMN_nHALT) with dominant recessive behaviour. IF_CMN_nHALT shows the driver core status. When IF_CMN_nHALT is HIGH (recessive), the driver core is ready to operate. When IF_CMN_nHALT is LOW (dominant), the driver core is disabled / not ready to operate because of e. g. detected failure or driver core system start. A controller can hold with the IF_CMN_nHALT signal the driver core in a safe state (e.g. during a start up of a system or gathered failure signal of other hardware) or generate a coeval release of paralleled driver. Furthermore, paralleled drivers can send and receive IF_CMN_nHALT signals among each other by using a single-wire bus.

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 If no temperature sensor is connected: R172: 0 R175: not equip R177: not equip (factory setting: not equipped) (factory setting: equipped) (factory setting: not equipped)
If a NTC temperature sensor is connected: 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 according to the IGBT Module explanation. 3. The trip level on the adapter board is set with R172 (factory setting: not equipped) by using the calculated resistance value. 4. R177 = 450k2 / RNTC(@ -40C)[k] (factory setting: not equipped) 5. R175: equip (factory setting: equipped) If a PTC temperature sensor is connected: 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 according to the IGBT Module explanation. 3. The trip level on the adapter board is set with R177 = 450k2 / Rcalculated_resistance[k] (factory setting: not equipped) 4. R172 = 0 (factory setting: not equipped) 5.

Mounting Notes
Driver Core Mounting
1. Soldering of components (e.g. RGon, RGoff, etc.) on evaluation board. 2. Insert driver core into the box connector on evaluation board. 3. The connecting leads between board and power module should be as short as possible (max. 20cm), the leads should be twisted.
The connection between driver core and evaluation board should be mechanical reinforced by using support posts. The posts have to be spaced between driver core and evaluation board. Product information of suitable support posts and distributor contact information is available at e.g. http://www.richcoinc.com (part number MSPM-8-01).
