Abstract

An important issue of compensating reactive power to enhance power quality is proposed in this paper. Non-linearity in circuit element characteristics causes reactive power to flow in circuit. A new topology faded with T shape ZSI operating on Maximum Constant Boost switching has been proposed to compensate the reactive power. Reactive compensators are a part of FACTS devices family. Here VAR compensation is being done by T shaped ZSI. We have applied max constant boost switching pattern to generate shoot through stages. To achieve better dynamic performance , as supplementary PI controller has been used to track reference value for zero reactive power and further this controller output signal is used to design switching pattern of maximum constant boost control for T shape ZSI.
