[Software EngineeringMULTIPULSE-CONVERTERS

Description: This paper discusses the impact of using 3-phase and multipules converter circuit commonly found in unity power factor at input AC mains and regulates output voltage.3-phase thyristor rectifiers have been used in industries for obtaining a variable DC voltage, but they have a problem of including large lower-order harmonics in the input currents. For high-power applications, a 12- pulse, 18-pulse and 24-pulse configuration is useful for reducing the harmonics, but it still includes the (np±1) th (n: integer, p: pulse) harmonics. In this paper present the rectifiers are using the MATLAB/SIMULINK simulation model and several common conditions will be simulated to compare their harmonic levels.

[Booksbackstepping

Description: The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system. The system structure includes a PV generator, Boost converter, and DC-AC inverter coupled to grid network. A backstepping controller is developed to extract maximum point power tracking (MPPT), to regulate the DC bus voltage, and to generate a sinusoidal current into the grid in phase with grid voltage in order to achieve unity power factor. The stability of the control algorithm is demonstrated by tools of Lyapunov analysis. Simulations show that the proposed controller system completely accomplishes listed aims even under atmospheric conditions variation. Theperformance of the proposed controller has been validated by numerical simulation in MATLAB SIMULINK(The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system.
