Abstract
In a drive circuit of a half-bridge inverter circuit, a stable operation cannot be performed at a start-up time and a problem exists such that if a high side output signal is first outputted, main switching elements and are simultaneously turned on. In the present invention, a start-up circuit comprising a latch circuit and a gate circuit are provided, the latch circuit is set while prioritizing a low-side signal, and a low-side output signal is always first made high level, thereby realizing a half-bridge inverter circuit which can start up wit a stability.
