DESIGN AND ANALYSIS OF A GRID-CONNECTED PHOTOVOLTAIC POWER SYSTEM

MODULE SEPERATIONModule 1: Steady-State Model of High Step-Up ZVT-Interleaved Boost ConverterModule 2: Control Strategy of Full-Bridge Inverter with Bidirectional Power Flow

MODULE 1 : STEADY-STATE MODEL OF HIGH STEP-UP ZVT-INTERLEAVED BOOST CONVERTER

Zvt ZVT- zero voltage transitionThis is the type of the resonant converters. Thats we are getting a sine wave output Resonant converters is based on combination of inductors and capacitors

MODULE 2: CONTROL STRATEGY OF FULL-BRIDGE INVERTER WITH BIDIRECTIONAL POWER FLOW

PID controlClosed loop control system is used to attain the stable of the system.Proportional control is used top reduce the effect of rising timeIntegral control is used to reduce the steady state errorDifferential control is used to obtain the transient response of the system
