Title:
TRAPEZOIDAL FIRE PULSE GENERATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2009/121296
Kind Code:
A1
Abstract:
A trapezoidal fire pulse generation method and device are provided, for determining the voltage values of a positive direct current control voltage signal and a negative direct current control voltage signal, and the voltage values of a rise time direct current control voltage signal and a fall time direct current control voltage signal of the pulse amplitude according to the trapezoidal fire pulse parameter value that is required to be outputted, and generating the corresponding direct current control voltage signal; the positive direct current control voltage signal and the negative direct current control voltage signal are modulated into square wave pulse; the rise time direct current control voltage signal, the fall time direct current control voltage signal and the square wave pulse are inputted into a reverse integrator to generate a trapezoidal fire pulse; the rise time parameter value of the trapezoidal fire pulse and the voltage value of the rise time direct current control voltage signal, and the fall time parameter value of the trapezoidal fire pulse and the voltage value of the fall time direct current control voltage signal have certain special magnitude relations, the method and device realize the control and adjustment of the rise time and fall time of a trapezoidal fire pulse, thus making the output trapezoidal fire pulse more stable and accurate.
