The basic boards have a zener diode on each channel for over-voltage protection. When the feed
voltage exceeds 16 V, this protection may be exposed to thermal overload.
If the specified power consumption is exceeded, this indicates an overload of the DC/DC converter.
It should be noted that these DC/DC converters are not protected against overload.
Application-specific self-heating of gate drivers and IGBT modules, especially at high switching
frequency, must be taken into account. As a rule, the switching frequency is limited due to the
switching losses of the IGBT modules. Because CONCEPT cannot predict how the drivers will be
incorporated in the user’s application, no binding recommended value for self-heating and thus for
the maximum useable output power can be made. Users are therefore recommended to check the
gate driver’s ambient temperature within the system.
Under-voltage monitoring of the supply voltage to the gate driver. If the voltage drops below this
limit, the power modules are switched off.
The driver can operate at switching frequencies up to 100 kHz. However, the switching frequency
is usually limited by the available power of the built-in DC/DC converter. The applicable power
depends upon the particular EconoDual IGBT module. See the data sheet of the relevant basic
board.
First value: At a load of 39 nF in series with 5.6 Ohms. Second value: At a load of 250 nF in series
with 1.8 Ohms. The delay refers to the direct output of the gate drive unit (excluding the delay of
the gate resistors).
The gate current is limited by the gate resistors located on the basic board.
The typical blocking time after an error is 1 second. Versions with other blocking times may also be
supplied if required.
This specification guarantees that the drive information will be transferred reliably even at a high
DC-link voltage and with ultra-fast switching operations.
The partial discharge is not measured for the standard types. Tested and selected types with
guaranteed partial-discharge immunity can be supplied for applications with maximum
requirements and higher operating voltages (such as railroad applications).
The test voltage of 4000 V
noted that with this (strictly speaking obsolete) test method, some (minor) damage occurs to the
insulation layers due to the partial discharge. Consequently, this test is not performed at CONCEPT
as a series test. In the case of repeated insulation 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 400 V for each additional test. The more modern if more elaborate partial-discharge
measurement is preferable to such test methods as it is almost entirely non-destructive.
