本文研究了双边沿脉宽调制控制降压型变流器的非线性行为。利用一个切换周期内的状态转移矩阵(单调矩阵)(包括每个切换过程中的状态转移矩阵(突变矩阵))来分析系统的稳定性。采用三种监控方式延长系统正常运行周期一次。理论分析、数值模拟与实验结果吻合较好。
The nonlinear behaviour of the buck converter controlled by double-edged PWM waveform is studied in this paper. The stability of the system is analyzed using the state transition matrix over one switching cycle (the monodromy matrix) including the state transition matrices during each switching (saltation matrices). Three supervising control methods are applied to extend the normal period one operation of the system. Good agreement is demonstrated between theoretical analysis, numerical simulations and the results are experimentally verified.
