Abstract

The four-switch three-phase (FSTP) SEPIC inverter with fuzzy controller has been proposed as an innovative inverter design to reduce the cost, complexity, size, and switching losses of the DC-AC conversion system. Fuzzy conroller can generate five different PWM pulses. A novel design for the FSTP inverter based on the topology of the single 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 factor of the input DC supply, where the proposed topology provides higher output line voltage which can be extended up to the full value of the DC input voltage. Simulation model and experimental setup are used to validate the proposed concept. Simulations and experimental results show the effectiveness of the proposed inverter.
