Abstract
Abstract: Now-a-days with the advancement in technology there is a drastic improvement in the semi-conductor devices. With this development and advantages, the semi-conductor devices got a permanent place in the power sector helping to ease the control of overall system. Moreover, most of the loads are also semi-conductor-based equipment. But the semi-conductor devices are non-linear in nature and draws non-linear current from the source. And also, the semi-conductor devices are involved in power conversion, which is either AC to DC or from DC to AC. This power conversion contains lot of switching operations which may introduce discontinuity in the current. Due to this discontinuity and non-linearity, harmonics are present which affect the quality of power delivered to the end user. To maintain the quality of power delivered, the harmonics should be filtered out. Thus, a device named Filter is used which serves this purpose.
