EconoPACKTM 4 3-Level Modules
V1.1 February 2014
1 Introduction
TM
The evaluation driver board F3L2020E12-F-P_EVAL for 3-level NPC2 EconoPACK 4 modules as shown in
Figure 1 was developed to support customers during their first steps designing applications with
TM
EconoPACK 4 3-level NPC2 modules. This evaluation board was designed in addition to the module
1
adapter board MA3L120E12_EVAL or could be a complementary part for an existing customer driver
solution. For more details about the 3-level topology, please refer to [1].
The board is available from Infineon in small quantities. The properties of this board are described in the
design feature chapter of this document, whereas the remaining paragraphs provide information to enable
the customers to copy, modify and qualify the design for production, according to their own specific
requirements.
Environmental conditions were considered in the design of the F3L2020E12-F-P_EVAL. Components
qualified for a lead-free reflow soldering process were selected. The design was tested as described in this
document but not qualified regarding manufacturing and operation over the whole operating temperature
range or lifetime.
The boards provided by Infineon are subject to functional testing only.
Due to their purpose evaluation boards are not subject to the same procedures regarding Returned Material
Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products.
See Legal Disclaimer and Warnings for further restrictions on Infineon‟s warranty and liability.

4 Functionality of the board
The F3L2020E12-F-P_EVAL driver board is a complementary part of the evaluation kit to drive one 3-level
TM
IGBT Module as displayed in Figure 7. The adapter board should be pressed to the EconoPACK 4 as
described in the AN2010-06.

Power supply
Four external power supplies for the IGBT driver ICs and external booster stages are needed. These
-8V/+15V power supplies are applied to the F3L2020E12-F-P_EVAL board using connector X2 as depicted
in Figure 8.
The logic side has to be powered with +5V via the connector X1 also represented in Figure 8. Further pin
assignments can be found in Table 6 and Table 7 on page 8.
Figure 8: Principle diagram of the F3L2020E12-F-P_ EVAL
The 1ED020I12-B2 IGBT driver IC monitors the supply voltage and activates the Under Voltage Lock Out
(UVLO) as soon as the supply voltage drops below the UVLO reference value.

Application Note AN2013-04
V1.1 February 2014
Input stage
The Evaluation Driver Board is designed for one leg of a 3-level IGBT configuration; therefore it is necessary
to apply four separate PWM signals dedicated to each IGBT. Schematic details for a single IGBT driver are
depicted in Figure 9.
Figure 9: Schematic details of the input stage for a single IGBT driver.
It is possible to choose positive or negative logic according to individual designs. For the use of IN+ as PWM
input, the IN- pin can be used as enable signal pin.
For the use of IN- pin as PWM input, the IN+ pin can be used as enable signal pin.
If the power supply voltage of the logic side exceeds the power-up voltage VUVLOL1 and the power supply
voltage of the high side exceeds the power-up voltage VUVLOH2, green RDY LEDs shown in Figure 10 for
IGBT1 to IGBT4 are turned on.
4.3
Short circuit detection
Short circuit is monitored individually by the four IGBT driver channels. Each of the four channels provides
an independent fault signal; they share a common reset input. Failure handling of the high and low side IGBT
has to be part of the superordinated control.
When a short circuit occurs, the voltage increase across the IGBT is detected by the desaturation protection
of the 1ED020I12-B2 and the IGBT is turned off. The fault is reported to the primary side of the driver as a
low active signal. Red LEDs /FLT_T1 to /FLT_T4 as presented in Figure 10 are turned on to signalize the
failure condition. The fault status remains active as long as there is no reset signal applied to the driver. The
/FLT signal is active low.

Output stage
The output stage of the F3L2020E12-F-P_EVAL as depicted in Figure 11 is prepared to be connected to the
complementary MA3L120E12_EVAL evaluation module adapter. The module adapter is directly plugged to
TM
the 3-level EconoPACK 4 module as shown in Figure 7 on page 10. The MA3L120E12_EVAL evaluation
board consists of an active booster stage to provide the necessary switching power, demanded by the IGBT
module.
Figure 11: Schematic details of the output stage for a single IGBT driver
For further and more detailed information on the 1ED020I12-B2 please refer to the Infineon datasheet.
5 Paralleling
The F3L2020E12-F-P_EVAL was designed to work with the evaluation adapter board MA3L120E12_EVAL
as single unit as depicted in Figure 7 on page 10 or to allow the parallel connection of up to three modules,
each equipped with one MA3L120E12_EVAL adapter board as represented in Figure 12. In case of
paralleling, the driver board does not need to be plugged into the complementary adapter board. The
connection from the driver to the adapter boards is done utilizing the connectors on the top side of the driver
board as shown in Figure 13.

Figure 13 displays a parallel connection of three 3-level IGBT modules. In this case it is necessary to assure
the same length of the gate wire between the driver and adapter boards to obtain the same run time of the
gate signals for the three IGBTs. Star connection of the IGBTs reduces the cross flow in the emitter lines
after the switching sequence. The F3L2020E12-F-P_EVAL driver board allows to switch up to three IGBTs in
parallel.
