摘要
目标函数是智能算法优化逆变器性能的评估标准.针对逆变器的目标函数考虑不够全面,需要提高逆变器整体性能等问题,提出了一种可以反映逆变器多个性能指标(电压精度、电压的总谐波失真、逆变器的效率以及功率器件的结温性能等)的目标函数,通过智能算法有助于提高逆变器的整体性能.最后以通过粒子群优化算法优化的单相离网逆变器为例,验证了所提出的目标函数的有效性.
The objective function is the assessment criteria for the intelligence algorithms to optimize the performance of the inverter.Aiming at the problems that the objective function of the inverter is not comprehensively considered and the overall performance of the inverter needs to be improved,an objective function that can reflect the multiple performance indicators of the inverter is proposed in this paper,which helps to improve the overall performance of the inverter through the intelligence algorithms.The proposed objective function can reflect the voltage accuracy,the total harmonic distortion(THD)of the voltage,the efficiency of the inverter,as well as the junction temperature performance of the power device.Its feasibility is verified through the single-phase off-grid inverter optimized by the particle swarm optimization algorithm.
