output load in conjunction with the present gate resistors leads to an additional delay at their load
side.
23) Delay of external fiber-optic links. Measured from the driver secondary side (ASIC output) to the
optical receiver on the host controller.
24) Measured on the host side. The fault status on the secondary side is automatically reset after the
specified time.
25) Including the delay of the external fiber-optic links. Measured from the transition of the turn-on or
turn-off command at the optical transmitter on the host controller side to the transition of the
acknowledge signal at the optical receiver on the host controller side.
26) The gate resistors and the auxiliary gate capacitor are not assembled on this IGBT gate driver. They
must be assembled by the user according to the paragraph on “Gate Resistor Assembly”.
27) The driver secondary side voltage is split into two distinct voltages on the driver. The first one is the
turn-on voltage which is regulated at about 15V. The difference between the total secondary side
voltage and the turn-on voltage is the turn-off voltage which is not regulated and mainly dependent
on the driver input voltage VDC and the DC/DC converter power.
28) Partial discharge measurement is performed in accordance with IEC 60270.
29) Clearance and creepage distances are designed according to IEC 60077-1. Refer to the “Description &
Application Manual for 1SP0635 SCALE-2 IGBT Drivers” for more information.
30) The fault status is set as long as the gate monitoring fault is present. The given value applies if the
driver goes from the “off state” to the “on state” and the gate-emitter voltage of one or more parallel
connected drivers does not turn on. If the driver goes from the “on state” to the “off state” and the
gate-emitter voltage of one or more parallel connected drivers does not turn off, the fault status is
applied as long as the gate monitoring fault is present.
31) The maximum switching frequency is not defined, as it depends on the IGBT module used. Please
consult the corresponding driver data sheet for more information.
