Abstract:
A pulse generation circuit configured to provide a first pulse and a second pulse to a switching device drive circuit in response to input signals, characterized in that:a first input signal which level-shifts between a first logic value and a second logic value having an exclusive relation with said first logic value, is inputted to said pulse generation circuit, and a second input signal, or, in addition to said second input signal, a third input signal is inputted to said pulse generation circuit, and said pulse generation circuit outputs a first pulse on level-transiting of said first input signal from said first logic value to said second logic value when said second input signal, or, in addition to said second input signal, said third input signal is not inputted, and said pulse generation circuit outputs a second pulse on level-transiting of said first input signal from said second logic value to said first logic value when said second input signal, or, in addition to said second input signal, said third input signal is not inputted, and said pulse generating circuit simultaneously output said first and second pulses when said second input signal, or, in addition to said second input signal, said third input signal is inputted.
