| 3ULQWHG &LUFXLW %RDUG IRU 6.+, $ DQG 6.+, $% GULYHUV 6.3& Preliminary Data )HDWXUHV www..com Fig. 1 Schematics * * * * J1, J2; Open => used with external distributing gate board for paralleled IGBTs (CN2 and CN3 only). Closed => used with single IGBT or 2 paralleled IGBTs (CN2, CN3, CN4 e CN5). * for low logic error; close J3. * for high logic error; build dashed circuit and open J3. Shield: J4 connects pin 1 of CN1 to GND when closed. * includes an inverter for driver error signal (capability). * able to connect single and paralleled IGBT modules. * same dimensions of SKHI 10 driver. * uses same input connector and pinouts as SKHI 23 driver. * glass fiber epoxi (UL). * ready for wave soldering. * connectors included * SKPC 22/2 normally should be completed by the customer, but it can be made available with parts fitted, on request. * see SKHI 21A, 22A/B datasheet to choose components values.
