CE 2.1 Project InformationName of the project: Design and development of PFC through VFDLocation of the project: KarachiProject Duration:(Please fill)Organization:(Please fill)Role and Designation during the time: Team MemberCE 2.2 Project BackgroundCE 2.2.1 Characteristics of the projectI had conducted this project to design and develop of Power Factor Correction (PFC)throughout Variable Frequency Drive (VFD). In this project, induction motor is used for meetingclient’s requirements. When there is supply of power to induction motor at recommendedspecifications, then it runs at high speed. Driving in addition to controlling of induction motorare the major concerns into energy aware world. There is availability of VFD into various AC-AC as well as DC-DC topologies to correct of the power factor. The topologies are used intoopen as well as close loop where in this project work, open loop system is mainly focused. CE 2.2.2 Objectives developed for the projectFollowing are the objectives to develop PFC AC drive through VFD:To design and develop of compact and low cost PFC AC DriveTo reduce of electricity bills

Figure 1: People involved in the projectCE 2.2.5 My responsibilities throughout the projectI had provided the description of the power semiconductor devices to the team membersso that they are aware of the project requirements. I had provided justification of the sinusoidalPWM switching techniques is followed by the switch mode converter as well as its types. I hadreviewed the end used isolation types. CE 2.3 Distinctive ActivityCE 2.3.1 Comprehending the Theory of the projectI had drawn the block diagram for PFC ac drive. There is rectifier which converts acinput to unregulated dc voltage. The harmonics into the filter is removed by the filter capacitor inorder to generate of three phase ac for the electric motor. When the load is overhauling themotor, then there is a rise into the dc bus voltage. The overvoltage is being sensed by dc-dcconverter and energy within the bus capacitor is being relocated into energy storage part.
