Hardware Implementation of Solar Assisted Automatic Curtain Control System

An innovative effort on hardware design of an automatic curtain control system powered by solar PV array. To achieve the objective, a constant voltage controller (CVC) type maximum power point tracking (MPPT) method for PV system is implemented with a DC to DC boost converter circuit to fond maximum power. Also, a motor controller unit is implemented to control the motor run time used in this system. The proposed system circuits which include CVC-MPPT circuit boost converter and motor control unit have been designed using Proteus environment. The closing and opening of curtain has been tested under different light intensity level. The performance analysis of entire system is observed acceptable.
