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. Since there are specific quantitative relations between the rise time and fall time of the trapezoidal fire pulse and the voltage values of the rise-time and fall-time DC control voltage signals, the corresponding rise time and fall time of the trapezoidal fire pulses can be accurately controlled and adjusted so that the outp…
