| Abstract: | In order to drive the piezoelectric-transformer inverter in airbag,a frequency-adjustable SPWM generator based on FPGA is designed in this paper.The article presents the principle design,the overall framework and the implementation and simulation results.The simulation results show that the design of the SPWM pulse-signal generator is a good solution to driving the piezoelectric-transformer inverter which has variable working frequency and also is difficult to drive. |
