Sliding Mode Control for Three Phase PV Grid Connected Energy System Using LCL Filter
In this research, a sliding mode control (SMC) was designed for controlling the grid connected photovoltaic (PV) power system. The proposed controller is affected of the current dynamic response of the system. Time domain simulations of a grid-tied three-phase inverter with active power injection subjected to major disturbance is investigated. The simulated results show the robustness of the proposed sliding ... إقراء المزيد

Performance Evaluations of Interleaved ZCS Boost DC-DC Converters Using Quasi-Resonant Switch Blocks for PV Interface
ABSTRACT: This paper presents a novel circuit topology of voltage source multi resonant ZCS interleaved boost DC-DC converter with auxiliary quasi-resonant lossless inductor snubbers and capacitor snubbers. It uses two feedback loops, similar to current mode control, one for slow outer loop and the other for faster inner PWM control loop. To improve the transient response of the 2-cell converter ... إقراء المزيد
