Active filters for motor drives have become one of the vital parts of an electric system particularly in industrial systems and renewable energy systems. These filters are installed in motor drives systems used to extinguish harmonics caused by nonlinear loads and hence improve the general power quality. It is possible to install active filters in the motor drive systems such that the energy lost is noticeably lowered, the operational mesh intensity increased and working life of the equipment components lengthened. Owing to the innovative nature of Sinotech Group all our active filters come with the latest technology since the power industry is always changing.
