This paper proposes an amplitude-modulated inverter with a 3-level DC-DC converter system for utility interactive photovoltaic power system. This system is composed of the DC-DC converter, which generates a fully rectified sinusoidal waveform, and the inverter, which is synchronized with utility system. From the experimental results, we concluded that the proposed system has high efficiency and sinusoidal current with unity power factor in the utility system, and it is useful for utility interactive photovoltaic power system.
