| 摘 要： | 扰动法观察法是光伏电池MPPT控制中常用的一种控制方法,稳态下扰动的步长与周期决定了占空比变化的范围。占空比变化过大会造成Boost电路输出功率波动大。文中通过分析与仿真证明了Boost电路中电感与旁路电容对扰动周期的影响以及扰动调节周期对Boost输出功率的影响。

| Abstract: | Perturbation method of observation is a control method in photovoltaic cell MPPT control~ steady state per- turbation step and frequency determine the duty cycle range. Duty cycle change is big could lead to the fluctuation of output power of the boost circuit. This article through the analysis and simulation proves that the boost circuit inductance and by- pass capacitors to the disturbance frequency effect and disturbance adjusting frequency on the output power of the boosteffect. |
