Abstract:

The SEPIC based inverter with reduced amount of switches has been proposed as an innovative inverter design to reduced cost and complexity.The four switch three phase (FSTP) SEPIC based inverter have less switching losses of the DC-AC conversion system. FSTP inverter operates at half the DC input voltages, so the output line voltage cannot exceed this value. The proposes a design for the FSTP overcome this problems and produced pure sinusoidal without need of filter in output side. The proposed topology produce output line voltage which can be extended up to full value of the DC line voltage. The Fuzzy control is used with proposed topology to ensure the robustness of the system. Fuzzy logic allows, solving difficult simulated problems with many inputs and output variables. The parameters, component ratings, and the operation of the proposed SEPIC inverter is described in this paper. Experiment and simulation shows the effectiveness of the proposed inverter.
