| titleOfInvention | Power device series connection voltage-sharing circuit containing device junction temperature and method thereof |
| abstract | The invention discloses a series voltage-sharing method for power devices containing device junction temperature, and belongs to the technical field of power electronic conversion. In the actual operation of the series voltage-sharing circuit, the unbalanced voltage of the series devices is closely related to the internal parameters of the devices and the external operation conditions. The series voltage-sharing strategy obtains unbalanced voltage and temperature among the series devices by extracting turn-off voltage, turn-on current and device temperature of the power devices, and is used for adjusting turn-off delay time of driving signals of each path of power device, so that power series voltage sharing is realized. The invention is suitable for medium-high voltage high-power application occasions, and the voltage-sharing adjustment has rapidity, instantaneity and higher stability. |
