ZETA Converter based charge controller for efficient use of solar energy in street lighting system

Faizan Hameed, Khalid Iqbal

The paper presents ZETA converter based solar charge controller with the function to disconnect the battery during overcharging or deep-discharging for efficient use of solar energy in street lighting system. Purpose of circuit’s designed is to charge the battery between upper and lower voltage limits in addition to continuously checking the status of charge of battery to add or release current accordingly. The designed circuit will provide alternative path to the power when battery is fully charged. Main difference between the method used in the proposed system and other techniques used in the past is that ZETA converter itself will act as charge controller in addition with this, specific properties of ZETA converter will be used to optimize street lighting system to reduce the power losses and cost. The designed circuit is also implemented in MATLAB using SIMULINK. So in concept of centralize architecture of PV street lighting system this design will provide a best alternative solution.
