Abstract
The reliability, efficiency, and controllability of Photo Voltaic (PV) power systems can be increased by embedding the components of a Boost Converter. Technology of boost converter should overcome the main problems of manufacturing cost, efficiency and production. The key factor to limit the life span of a PV inverter is the huge electrolytic capacitor across the Direct Current (DC) bus for energy decoupling. A boost converter is a DC-DC power converter with higher output voltage, but it produces some ripple current. In order to improve the efficiency of the boost converter and reduce the ripple current, an interleaved boost converter is used. This paper presents a two-phase interleaved boost converter which ensures 180° phase shift between the two interleaved converters. This paper presents a two phase Interleaved Boost Converter with Proportional Integral (PI) controller. PI is designed for output voltage regulation and this boost converter is simulated for various Pulse Width Modulation (PWM) scheme. This simulation results shows output voltage is well tracked and it improves the efficiency and reduces the ripple current.
