Two operation modes for the 2ED300C17-S EiceDRIVER™ are possible:
•
•
Table 8
The 2ED300E17-SFO is already equipped with C4=C5=470pF meaning that when JP1 is on position H-M
than interlocking time between channel A and B will reach 5,4µs.
3.5
The ‘Soft Shut Down’ function secures an IGBT module when short circuit current is being switched off. This
function is widely described in 2ED300C17-S EiceDRIVER™ application note (chapter 3.8). Resistor called
R
channel B and should be selected accordingly to module type.
These resistors originally are not soldered. In order to provide the correct SSD function resistors R3, R31, R4
and R41 must be properly calculated. The calculation example is shown bellow:
where:
Qg – gate charge of selected IGBT module type
Due to resistors parallel connection the final value gives formula 3.
When PrimePACK™ modules are used than Table 9 shows already calculated R

Direct mode – means that both channels A and B are working accordingly to PWM signals. It is possibile
to switch on both channels A and B at the same time. This operation mode can be activated by setting
the JP1 jumper on position marked as D-M (shorting pins 1 and 2 on Figure 3). When jumper JP1 is used
there is no need to short X1.12 to GND of power supply
Half-bridge mode is especially usefull when IGBTs are driven in half bridge configuration. By proper
selection of capacitor values C4 and C5 the required dead time between channels A and B can be
provided. This operation mode can be activated by setting the JP1 jumper on position marked as H-M
(shorting pins 2 and 3 on Figure 3). When jumper JP1 is used there is no need to short X1.12 to V
Table 8 shows how dead time depends on these capacitors value. The dead time with not connected
capacitors is 1,6µs.
in the 2ED300E17-SFO is called R3, R31 (are in parallel) for channel A and R4, R41 (are in parallel) for
Direct or Half-bridge mode selection
