Installation Of The Eb1200M62-355Jc - Broadcom ACPL-355JC Reference Manual

ACPL-355JC Reference Manual
The analog input is continuously sampled by means of sigma-delta over-sampling using external clock, coupled across the
isolation barrier, which allows synchronous operation with any digital controller. The signal information is contained in the
modulator data as a density of ones with a data rate up to 20 MHz, and the data is encoded and transmitted across the
isolation boundary, where it is recovered and decoded into a high-speed data stream of digital ones and zeros. The original
signal information can be reconstructed with a digital filter.
Combined with superior optical coupling technology, the modulator delivers high noise margins and excellent immunity
against isolation-mode transients. With a 0.5-mm minimum distance through insulation (DTI), the ACPL-736J provides
reliable double protection and high working insulation voltage, which is suitable for fail-safe designs.
WARNING!
The EB1200M62-355JC gate driver evaluation board is designed to work with voltages up to 800V and thus
requires that all safety precautions and national accident prevention rules be undertaken. Installation and use
of the board should be reserved for skilled technical personnel. There is a danger of serious injury and property
damage if the board is not properly used or installed. It is strongly recommended that a system aimed to supply
the evaluation board be equipped with control and protection devices, in agreement with applicable safety
standards.
ATTENTION: Signals dedicated for the high-side driver and low-side driver must have proper dead time. The board itself
does not provide dead time generation. The recommended minimal dead time value is 500 ns.

3.5 Installation of the EB1200M62-355JC

Before starting with the evaluation of the board, consider and observe the following installation steps:
1. Before any installation, make a visual inspection of the board to ensure that it contains all components assembled except
the module. See Section A.3, Bill of
does not contain an assembled module to avoid damage to the module and the evaluation board during transport, as
well as to provide the customer the option to use other modules with the same footprint.
2. If a MOSFET module with a different part number from the default one is to be used, the high and low gate driving
voltages should be adjusted according to
of the gate driver circuit should be changed to accommodate the driven device.
3. Assemble the 62-mm module. The module gate/source driving pins must be soldered.
4. Make an electrical connection of +DC_bus and –DC_bus from the SiC module power terminals to the J6 and J7 terminals
on the EB1200M62-355JC eval board. The connection can be made with flying wires, or the eval board can be directly
attached to a custom-designed DC-link PCB over terminals J6 and J7 by screwing the terminals to the DC-link PCB.
5. Ensure that the over-current protection feature is well adjusted. Depending on the MOSFET module assembled,
readjustment of the OC Zener diode D2 (D12 for the low-side MOSFET) should be considered, as well as the additional
resistor R13 (R32 for the low-side MOSFET) for adjustment of the blanking time (see
6. With the available jumper, select the desired voltage reference for the current measurement. Available references are
5V and 3.3V.
7. Connect the user interface connector. The PWM signals as well as the ACPL-355JC output fault signals should be
connected to the control board with 5V logic.
8. Connect the +15V external power supply. The EB1200M62-355JC requests a +15V external power supply to enable +5V
and +3.3V digital operations and +14V and –4V default gate driver high voltage side power supply. Although the polarity
is marked, the board is reverse protected at the V
