PROJECT TITLE:

A Four-Switch Three-Phase SEPIC-Based Inverter - 2015

ABSTRACT:

The four-switch three-section (FSTP) inverter has been proposed as an innovative inverter design to reduce the price, complexity, size, and switching losses of the dc-ac conversion system. Traditional FSTP inverter sometimes operates at [*fr1] the dc input voltage; hence, the output line voltage cannot exceed this worth. This paper proposes a unique style for the FSTP inverter primarily based on the topology of the one-ended primary-inductance converter (SEPIC). The proposed topology provides pure sinusoidal output voltages with no need for output filter. Compared to traditional FSTP inverter, the proposed FSTP SEPIC inverter improves the voltage utilization issue of the input dc provide, where the proposed topology provides higher output line voltage that can be extended up to the total price of the dc input voltage. The integral sliding-mode management is employed with the proposed topology to optimize its dynamics and to make sure robustness of the system during different operating conditions. Derivation of the equations describing the parameters style, components ratings, and the operation of the proposed SEPIC inverter is presented in this paper. Simulation model and experimental setup are used to validate the proposed concept. Simulations and experimental results show the effectiveness of the proposed inverter.
