摘要

建立了一种新的脉冲宽度调制(PWM)过程的数学模型，实现了开关电源变换器的行为非线性仿真。利用拉普拉斯变换和Heaviside酉脉冲函数，建立了PWM脉冲的非线性数学模型。该数学模型导致了一个非线性的Simulink仿真模型，通过对摄动的验证，并用于获得不同的PWM技术，并用于促进dc - dc转换器和VSI的仿真。

New mathematical nonlinear modulator model for switch-mode pulse width modulated converter circuits

A new mathematical model of pulse width modulation (PWM) process is developed to attain behavioral nonlinear simulation of switch-mode power converters. Applying the Laplace transformation and Heaviside unitary pulse function, a nonlinear mathematical model of the PWM pulses is achieved. This mathematical model, which leads to a nonlinear Simulink simulation model, validated against perturbations and employed to obtain different PWM techniques and employed to facilitate the simulation of DC-to-DC converters and VSI.
