Abstract
A level shifting circuit, satisfying a requirement of a high tolerated dV/dt level, and a highly reliable inverter circuit, wherein a set pulse signal and a reset pulse signal, both of which are level-shifted to a potential side taking as reference a reference potential of a gate control terminal of a switching terminal, are obtained differentially and integrated, and, in case these pulse signals equal or exceed stipulated integrated values, are transmitted as regular control signals controlling the on/off state.
