Under Voltage Protection of driver power supply (UVP)
The internally detected supply voltage of the driver has an under voltage protection. The table below gives an overview of
the trip level.
Supply voltage
Regulated +15V ±4%
UVP level
13,5V
If the internally detected supply voltage of the driver falls below this level, the IGBTs will be switched off (IGBT driving
signals set to LOW). The input side switching signals of the driver will be ignored. The error memory will be set, and the
output PRIM_nERROR_OUT changes to the HIGH state.
Input Signals
The signal transfer to each IGBT is made with pulse transformers, used for switching on and switching off of the IGBT. The
inputs have a Schmitt Trigger characteristic and a positive / active high logic (input HIGH = IGBT on; input LOW = IGBT off).
It is mandatory to use circuits which switch active to +15V and 0V. Pull up and open collector output stages must not be
used for TOP / BOT control signals. It is recommended choosing the line drivers according to the demanded length of the
signal lines.
Please note:
It is not permitted to apply switching pulses shorter than 1µs.
TOP / BOT Input
A capacitor is connected to the input to obtain high noise immunity.
This capacitor can cause for current limited line drivers a little delay of
few ns, which can be neglected. The capacitors have to be placed as
close as possible to the driver interface.
Short Pulse Suppression (SPS)
This circuit suppresses short turn-on and off-pulses of incoming signals. This way the IGBTs are protected against spurious
noise as they can occur due to bursts on the signal lines. Pulses shorter than 625ns are suppressed and all pulses longer
than 750ns get through for 100% probability. Pulses with a length in-between 625ns and 750ns can be either suppressed or
get through.
