LEVEL SHIFT CIRCUIT, SWITCHING ELEMENT DRIVE CIRCUIT AND INVERTER APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a switching element drive circuit suppressing an erroneous decision by a common mode noise due to dv/dt of a level shift circuit and having high robustness, and to provide an inverter apparatus.

SOLUTION: A signal level of a setting load with an offset of the level shift circuit is compared with a signal level of a resetting load. It is determined that the level of the setting load becomes lower than the offset in comparison with the level of the resetting load, and a setting pulse is detected.
