Abstract

The utility model discloses a hybrid integration IGBT driving circuit which belongs to the technical field of power device driving. The circuit comprises a hybrid integration IGBT driving chip and a voltage regulation tube. The hybrid integration IGBT driving chip uses QP12W05S-37 (A). The voltage regulation tube uses DZ402 and DZ403. The voltage regulation tube is connected with the hybrid integration IGBT driving chip. An external signal undergoes current limiting of a resistor and is input to the hybrid integration driving chip. The hybrid integration driving chip outputs a stable voltage signal to drive IGBT on-off. The circuit has a function of output signal amplitude limiting, so as to ensure that signals received by an IGBT gate are in the safe range. At the same time, detection is carried out on current on both ends of the IGBT. When a current value exceeds a limit value, the driving circuit blocks output and sends out a wrong signal, so as to ensure the safety of IGBT. The hybrid integration IGBT driving circuit provided by the utility model has the advantages that the driving circuit is provided with a power supply and has the functions of fault blocking and restoring and protecting soft turn-off time adjusting.
