Infineon EconoPIM™ 3 IGBT Module EB1200-352J Evaluation Board
Chapter 5: Setup
WARNING!
The EB1200-352J board is designed to work with 600V and thus requires that all safety precautions and national
accident prevention rules must be undertaken and observed by skilled technical personnel, related to a board
installation, use, and maintenance. There is a danger of serious injury and damage of property if the board is
improperly used or installed. It is strongly recommended that a system aimed to supply the evaluation board is
equipped with control and protection devices, in agreement with the applicable safety standards.
ATTENTION:
Signals dedicated for high-side and low-side drivers, in one inverter leg, must have proper dead-time. The
board itself does not provide dead-time generation. The recommended minimal dead-time is 5 µs.
5.1 Installation of the EB1200-352J
Before evaluating the board, perform these installation steps:
1. Before any installation, make a visual inspection of the board to make sure it contains all components assembled except
the PIM module. See
, for the list of components. The EB1200-352J, by default, does not contain an
assembled PIM module to avoid damage of the module and the evaluation board during transport, as well as to provide
the customer an option to use other modules with the same footprint.
2. Ground the board. Connect the –DC_BUS terminal to earth potential.
3. Connect the signal connector. The PWM signals as well as the ACPL-352J output fault signals can be connected to any
control board with 5V/3.3V logic.
4. Connect a 24V external power supply. The EB1200-352J requests a 24V external power supply to enable 5V digital
operations and a ±15V gate driver high-voltage side power supply. Although the polarity is marked, the board is reverse
protected at the terminals of 24 V external supply.
5. Turn on power to the board by performing these steps:
– Case 1, with DC voltage:
a. Connect the DC power supply on terDC_BUS and –DC_BUS.
– Case 2, with three-phase AC voltage:
a. Use terminals N_REC and –DC_BUS to connect the external pre-charge circuit.
NOTE: Precautions:
Due to technical requirements, the evaluation board does not comprise a pre-charge circuit that
enables soft DC bus charging. In the case that the three-phase autotransformer is not used, an external pre-charge
circuit must be installed to avoid DC bus capacitor failure, which would cause injury and damage to property.
b. Use terminals L1, L2, and L3 to connect the three-phase AC power supply.
ATTENTION:
The maximum allowed input AC voltage is 480V.
