The following chapter describes functionality of the 2ED300E17-SFO in combination with 2ED300C17-S /-ST
EiceDRIVER™ in details.
3.1
The 2ED300E17-SFO provides +5V DC regulated voltage needed for fiber optic devices but also supplies
the 2ED300C17-S /-ST EiceDRIVER™. In order to get the EiceDRIVER™ properly working the external DC
voltage source must fulfill requirements mentioned in chapter 2.3 and Table 1.
3.2
The evaluation board offers two independend control interfaces: electrical and optical. The way of
communication with the EiceDRIVER™ can be selected by customer accordingly to the individual needs.
Electrical interface is simply activated by applying suitable signals
described in chapter 2.4, Table 4 and Table 5. Jumpers JPA and JPB visible on Figure 3 in that mode must
be open.
When IGBT is driven using optical interface the fiber optic cables should be connected to receiver XRA in
order to drive channel A and respectively XRB to drive channel B. Jumpers JPA and JPB in that case must
be closed (Figure 3). No electrical signals except power supply connected to X1 are needed. Other
connections should be removed. Keeping power supply connected to X5 or X6 and leaving X1 completelly
unconnected seems to be the easiest solution.
3.3
When the driver detects IGBT short circuit or V
switched off safetly and a fault will be reported. The event is additionally indicated by lighting diode D1.
Voltage on X1.3 changes from V
Regardless PWM signals the IGBT stays off and fault is indicated. In order to get driver operating again the
driver must be reseted in one of three possible ways:
•
•
•
Keeping the switch S1 pressed long time may lead to permanent IGBT destruction when the reason for short
circuit or low V
Reseting procedure is needed always after fault indication.
