The invention provides a signal logic conversion circuit which comprises an upper tube driving unit and a lower tube driving unit. A first input end of the upper tube driving unit is connected with first pulse input voltage. A second input end of the upper tube driving unit is connected with direct-current input voltage. A third input end of the upper tube driving unit is connected with an enablesignal. the upper tube driving unit is used for outputting a first pulse output signal according to a first pulse input signal, direct current input voltage and the enable signal so as to drive an upper side IGBT of a converter; the first input end of the lower tube driving unit is connected with the direct-current input voltage, the second input end of the lower tube driving unit is connected with a second pulse input signal, the third input end of the lower tube driving unit is connected with the enable signal, and the lower tube driving unit is used for outputting a second pulse output signal according to the secon
