基于模型预测控制的有源电力滤波器开关损耗优化设计
Optimized design of active power filter switching loss based on model predictive control
摘要
Abstract
The prediction model of the current output of the active power filter inverter was constructed by α-β coordinate transformation, and the optimal current control strategy was proposed to reduce the switching loss of the active power filter. The design used an evaluation function to evaluate the voltage vectors in different switching state of the inverter switching device for the sake of predicting all the possible compensation current values of active power filter. When the evaluation function value turned the smallest, the switch state corresponding to the voltage vector was applied to the next sampling period, acheiving the quick tracking of the harmonic reference current. The evaluation function increased the switching frequency of the additional term, by controlling the number of switching operations to realize the switching frequency drop. The simulation results showed that this control strategy could significantly reduce the switching frequency by optimizing the evaluation function and selecting the appropriate weight coefficient, ensure the balance between switching frequency and grid current, and effectively reduce the switching losses.关键词
