I n t e r n e t :
At a supply voltage greater than 16V, the open-circuit voltages on the two output sides of the DC/DC
converter may exceed 18V. This can lead to the destruction of the driver and protection circuits on the
output side.
Only internal consumption of the drivers, static.
The MTBF (mean time between failures) is calculated to MIL HDBK 217F at an ambient temperature of
40°C, a typical load and when the driver is exposed to a current of air. Further information on reliability
may be obtained from CONCEPT upon request.
The fiber-optic transmitters should always be driven by a current source or a voltage source with a pre-
connected resistor to limit the transmitter current to between 10 and 11 mA (see Fig. 2). The inputs must
never be connected directly to a low-resistance driver.
In the event of a fault, the driver turns the power semiconductor off almost without a delay. The
acknowledgement traverses the fiber-optic link that has a transit delay of about 100 ms. When the fault
message arrives at the control side therefore, the power transistor has already been in the turned-off
state for 100...500 ms.
At a load of 50 nF in series with 5 Ohm.
Maximum continuous or repeatedly-applied DC voltage or peak value of the repeatedly-applied AC
voltage between the inputs and outputs as well as between the power supply inputs and all other termi-
nals and between output 1 and output 2. However, types rated and selected for higher partial-discharge
voltages are also available (see note 8).
The partial discharge is not measured for the standard types. For main power applications, a sufficient
safety margin exists between the typical operating voltage of < 600Vdc and the partial discharge
extinction voltage of typically about >3000Vpeak. Tested and selected types with guaranteed partial-dis-
charge immunity can be supplied for applications with maximum requirements and higher operating
voltages (such as railroad applications).
The test voltage of 5000 Vac(rms)/50Hz may be applied only once during a minute. It should be noted
that with this (strictly speaking obsolete) test method, some (minor) damage occurs to the isolation layers
due to the partial discharge. Consequently, this test is not performed at CONCEPT as a series test. In the
case of repeated isolation tests (e.g. module test, equipment test, system test) the subsequent tests should
be performed with a lower test voltage: the test voltage is reduced by 500V for each additional test. The
more modern if more elaborate partial-discharge measurement is better suited than such test methods as
it is almost entirely non-destructive.
The application-specific self-heating of the drivers - specially at high load - must be taken into account.
The module has a self-heating of 20°C in absolutely still air (at its warmest internal point). The self-
heating can increase, depending on the load on the driver. If the drivers are exposed to a strong air
current, the self-heating is reduced by up to about 66%. The maximum ambient temperature is obtained
from the maximum operating temperature of +85°C for the IHD 580 FI (or +70°C for the IHD 580 FN)
less the self-heating. CONCEPT can perform measurements of the self-heating for critical applications
when the load (IGBT types and input capacitance) and clock frequency are specified.
