Method for driving power semiconductor switches for switch reluctance motors

The invention provides a method for driving power semiconductor switches for switch reluctance motors. Master controllers for the power semiconductor driving switches comprise DSP (digital signal processors) and FPGA (field programmable gate arrays). The method includes transmitting control signals Ctro[1:0], enable signals EN, EN and EN and driving signals A, B and C to the FPGA by the DSP; processing the control signals Ctro[1:0], the enable signals EN, EN and EN and the driving signals A, B and C by the FPGA and then generating driving signals A , A , B , B , C and C capable of directly driving the power semiconductor switches; processing the driving signals A , A , B , B , C and C by driving circuits and then transmitting the driving signals A , A , B , B , C and C to T, T, T, T, T and T on base electrodes for driving the power semiconductor switches. The method has the advantages that each controlsignal comprises 2 binary numbers, accordingly, four control modes can be generated and can be freely switche
