ABSTRACT:
A gate driving circuit having: a direct current power source; a driving signal source for outputting signal; a main switch device, having a gate terminal in which the signal outputted from the driving signal source is inputted, for controlling a conduction state between a source terminal and a drain terminal; a load energized when the conduction state between the source and drain terminals becomes a conductive state; a reverse current blocking unit, connected between the driving signal source and the gate terminal; and a regenerative unit, connected between the gate terminal and a high potential side of the power source, which becomes a conductive state when the conduction state between the source and drain terminals is a non-conductive state. A gate-source threshold voltage to obtain the conductive state between the source and drain terminals is set higher than an output voltage of the power source.
