  • Methods and devices for generating trapezoidal fire pulses
    Patent number: 8278976
    Abstract: The present application discloses trapezoidal fire pulse generating methods and devices. According to the devices and methods of the present application, the voltage value of the positive DC control voltage signal, the voltage value of the negative DC control voltage signal, the voltage value of the rise-time DC control voltage signal and a fall-time DC control voltage signal can be determined according to the parameter values of a trapezoidal fire pulse required to be output. Thus, corresponding DC control voltage signals can be generated. Further, the positive DC control voltage signal and the negative DC control voltage signal can be modulated to a square-wave pulse. Then, the rise-time DC control voltage signal, the fall-time DC control voltage signal and the square-wave pulse can be input to a inverse integrator so as to generate a trapezoidal fire pulse.
