扰动观察法的MPPT负载突变误判现象研究
On Misjudgment Phenomenon of MPPT Load Mutation Based on Perturbation and Observation Method
摘要
Abstract
In the photovoltaic system, Boost circuit acts as a preceding circuit to transmit maximum energy to backward circuit, achieving maximum power point. However, in the system operation, loading and offload in backward circuit adjustment may cause changes in equivalent input resistance. As a result, there will be some thing wrong with preceding Boost circuit power point, which may lead to misjudgment phenomenon. The paper focuses on effect of load mutation on circuit misjudgment when perturbation and observation method is applied to make MPPT. Misjudgment of the whole circuit process from adjusting to circuit steady state is analyzed and summarized. Finally,Boost circuit is established to verify its correctness.关键词
