Introduction
The 2ED250E12-F evaluation driver board shown in Fig. 1 was developed to support customers during their first design steps with the 1200V PrimePACK™ IGBT module. The evaluation driver board is a fully functional IGBT module driver where two 1ED020I12-F driver IC process control and feedback signals and provide galvanic insulation. An embedded isolated DC/DC converter supplies gate drive power to both IGBTs of a halbridge configuration.

Main features
The 2ED250E12-F Evaluation Driver Board offers the following features:
• Dual channel IGBT driver utilising the 1ED020I12-F1 driver IC
• Electrically and mechanically suitable for PrimePACK™ modules 1200V family
• Integrated isolated DC/DC power supply
• Integrated protection against DC/DC power supply short circuit
• Under Voltage Lockout
• Positive logic with CMOS logic level (5V) for PWM and Fault signals. Can be converted to negative logic
• Separated fault output and ready signal for Top and Bottom IGBT
• Separated ground potential for DC/DC power supply and input logic
• Different gate resistor values for turning-on and -off are possible
• IGBTs are protected against temporary VCE overvoltages during turn-off (Active Clamping)
• Diodes for IGBT desaturation monitoring implemented (short circuit protection)
• All components, except DC/DC transformer, are surface mount devices (SMD) with lead free 260°C soldering profile
• PCB is designed to fulfil the requirements of IEC61800-5-1, pollution degree 2, overvoltage category III
