2SD316EI compact, plug-and-play, dual-channel SCALE IGBT drivers are designed to suit all EconoDUALTM modules. They are based on CONCEPTs proprietary SCALE chipset, a proven technology that enables reliable driving and safe operation of IGBTs. Drivers are fully equipped with protection functions such as Vce-monitoring for short-circuit protection, operation inhibit after fault and supply-under-voltage shutdown.
2SD316EI drivers supply a gate current of +16A/-6A. Operating the gates with a bipolar control voltage (typically ±15V) allows IGBT modules to be driven reliably with high immunity to interference.
2SD316EI drivers feature an active clamping function - the most rugged and high-performance way to protect costly IGBTs.
An on-board DC/DC converter provides a self-contained, isolated 3W per channel power supply.
The electrical interface (DIC20) operates with a 15V logic level to ensure high noise immunity.
2SD316EI drivers support two independent driver channels or a half-bridge with internal dead-time generation.
Standard EconoDUAL modules cover several voltage and current ratings. Some driver parameters must, therefore, be matched to the relevant module. This is achieved by using a separate Base Board which is assembled and fully tested by CONCEPT. Because is only uses standard through-hole components it can be easily adjusted by the user to fit special requirements and applications.
The Base Board contains all gate resistors, gate-clamping and active-clamping diodes (overvoltage protection) as well as the diodes for the collector-sense function (surgecurrent and short-circuit protection). It also carries the components that are necessary for setting the turn-off trip level and the response time. The Base board can be soldered directly onto the IGBT module. The 2SD316EI driver is simply mounted on top of the relevant Base board using spacer bolts.
SCALE drivers have been established as an industrial standard since 1999. They have been tried and tested in many industrial and traction applications. The calculated MTBF according to MIL Hdbk 217F is 10 million hours at 40degC. According to field data, the actual reliability is even higher.
