Abstract
In this paper
the series hybrid active power filter(SHAPF) based on SVPWM is described
and its principle
design and application are introduced in detail. Simple and uncomplicated vector transformation is achieved by the active power filter and the switching numbers and loss are reduced within one switching cycle by the introduction of zero vectors. Meanwhile
the filtering efficiency of the SHAPF can be improved due to the higher utilization rate of DC busbar voltage and the smaller harmonics of inverters. Finally
the correctness of the method is verified through simulation and test.
