[background technology]
Solar electrical energy generation, wind-power electricity generation are very big by environmental influence, and the electric energy of generation can not be delivered directly to electrical network, and
Photovoltaic DC-to-AC converter, wind energy inverter ideally solve this problem.IGBT module is as photovoltaic DC-to-AC converter, wind energy inverter
Electric energy conversion pipe fitting device, the safety and reliability of its service behaviour is directly connected to the reliability of whole invertor operation,
IGBT drives burst pulse to be the key factor causing IGBT module to lose efficacy, and can affect greatly IGBT, even damage.
When just starting to open mainly due to IGBT or fly-wheel diode chip, be not the most full of carrier, now turn off IGBT or
Person's diode, current changing rate dic/dt person diF/ dt can increase, and owing to change of current path exists stray inductance, can produce higher
Turn off voltage overshoot and increase the reverse recovery current of diode.
Minimum pulse width suppression is to prevent from not having sufficiently long open or the turn-off time controls the open-minded of quasiconductor
Or turn off.Traditional method can employ hardware to realize, by a Schmidt trigger with functions of low-pass filter, logical
Cross RC and the suitable time be set, but exist the time can be caused to change due to the error of electric capacity and other devices deficiency it
Place.In order to solve the weak point that traditional method exists, improve the service behaviour of IGBT, it is necessary to propose a kind of IGBT burst pulse
Suppressing method.
[summary of the invention]
