AN 5946 Driving Dynex High Power IGBT modules with Concept Gate Drives Application Note AN5946-2.0 September 2009 LN26854 Author: Dinesh Chamund Introduction Dynex Semiconductor manufactures a variety of IGBT modules ranging from 1200V to 6500V and 100A to 2400A. Dynex do not manufacture gate drives for these modules but have made arrangement with CT-Concept Technologie AG of Switzerland to supply gate drives suitable for Dynex IGBT modules. who do not want to use the plug-and-play drivers with all the functionalities and want to design a dedicated driver for a specific application. Concept supplies two types of gate drivers: Plug-and-play drivers Driver Cores. Fig. 1 Plug-and-play driver Plug-and-play The plug-and-play drivers are supplied either independent of IGBT module manufacturers or dedicated drivers specific to manufacturers part numbers (Fig. 1). These drivers are complete and ready to use and more information regarding plug-and-play driver selection for the Dynex range of IGBT modules is available on the Concept web site. Also Dynex web site provides direct link to the appropriate web pages for quick navigation to the Concept web site. Driver Cores Driver cores are modules (Fig. 2) complete in every sense except they allow flexibility to match the devices and applications. This application note is targeted for those Fig. 2 Driver Cores The driver cores have all the basic functions such as electrical isolation, DCPage 1 of 7 AN 5946 DC converter to provide the driver power and protection circuitry. These are mounted on a circuit board with all the additional components required to match the driver to a specific IGBT module or application. These include input interface, gate resistors, active clamping and more. In this application note we consider driver type 1SD1548AI which is a single output gate driver Fig. 3 and 2SD160AI, 2SD160AI-17, 2SD315AI, and 2SD315AI-33 which are half bridge drivers. A block diagram of 2SD160AI half bridge driver is shown in Fig. 4.

The selected cores cover the IGBT module range from 100A to 2400A and voltage from 1200V to 3300V. Concept has recently introduced SCALE – 2 Driver cores suitable for IGBTs from 600V to 1700V. Drivers selected from this range are shown in Table 2.

AN 5946 Dimensioning Driver Core When selecting a suitable driver for the IGBT module following considerations should be taken into account. The required isolation for the module voltage rating The driver should be able to provide the required power datasheet values. Note that fmax is the maximum frequency the gate drive can be driven for a given IGBT module part number. This not necessarily means a module can be switched at this frequency as the power losses in the device and device cooling arrangement may not allow the device to be operated at this frequency. Concluding remarks The driver should be able to deliver the required gate current. The gate power Pgate is given by the equation (1). Pgate = fge*Q*ΔVge (1) Where fge is the gate driving frequency The gate drive recommendations are based on the Dynex datasheet values and Concept gate driver specification. The final choice of the gate driver depends very much on the applications. Users are highly advised that they should read the Concept gate driver application notes posted on their web site and adhere to all the tips and recommendations made in these application notes. Additional support and information on Concept gate drivers can be obtained from: Q is the gate charge ΔVge is the change in gate voltage The maximum output current of the gate driver should be equal or greater than the required maximum gate current. This is given by equation (2). CT-Concept Technologie AG IGmax = ΔVge/RGmin CH-2504 Biel-Bienne (2) Note that different values of RG are sometimes used for turn-on and turn-off gate resistor; in this case the minimum value should be considered. Tables 3, 4 and 5 give gate drive selection charts for the 1200V, 1700V and 3300V IGBT modules respectively. These charts are constructed using the relations given in the equations (1) and (2) for the Dynex Intelligent Power Electronics Renferstrasse 15 Switzerland.
