In this paper it is presented a detailed description of the analog implementation of the control for a DC-AC converter composed by a DC-DC Zeta converter and a low frequency inverter. Using only analog components, it was developed the MPPT technique based on linearization of solar panel characteristic around the MPP, a feedforward control and a robust PWM sine wave modulator. This simple and low cost...
This paper presents the study and development of a processing power system to be used in the grid connection of renewable energy sources to the power grid. The system consists of a Zeta converter associated with a full bridge inverter operating at low frequency. The Zeta converter, operating in discontinuous conduction mode (DCM), plays the main role in this arrangement, producing a rectified sinusoidal...
