Abstract

A novel Parallel Hybrid Active Power Filter topology without transformer proposed is against the problem of excessive subharmonic content and insufficient reactive power in some cases

which consists of active and passive parts

and it increases active part to compensate harmonics on the basis of passive part to realize reactive power compensation. The system makes use of the working characteristics of the passive part series partial voltage and series resonance to reduce the active part working voltage low

and then reduce the capacity of the active part. After analyzing the working characteristics of the new topological circuit

a mathematical model of the system is established

using the decoupling control method to achieve effective control of the system. Experimental results confirm the feasibility and advantages of the proposed method.
