The invention discloses an automatic double-
pulse test system and method, and the
system comprises an upper computer unit, a controller unit, a
capacitor charging and discharging loop unit, a load
inductance unit, an IGBT
power unit, and an
oscilloscope unit, the upper computer unit is connected with the controller unit, the controller unit is connected with the IGBT
power unit, and the
oscilloscope unit is connected with the
capacitor charging and discharging loop unit. The control end of the controller unit is connected with the input ends of the
capacitor charging and discharging loop unit and the load
inductance unit, and the output ends of the load
inductance unit, the capacitor charging and discharging loop unit and the
oscilloscope unit are respectively connected with the IGBT
power unit. The whole operation process can be realized through an upper computer. Full-
automatic control and
electrical isolation of the whole double-
pulse test loop are realized through the controller, so that the test safety is effectively guaranteed; the turn-on and turn-off resistors driven by the IGBT can be adjusted on line, the operation is convenient, and the
test efficiency is greatly improved; most IGBT double-
pulse test scenes can be met, and the IGBT
power module and the capacitor module can be directly and quickly connected with the
system for testing.
