Recently, Power Conditioning System (PCS) tends to require more compact, higher efficiency and power density with better performance. A novel topology consisted of LLC resonant inverter and Low Frequency (LF) cyclo-converter for connecting to utility line is able to meet these requirements. The technical operating analysis is described and 1kW prototype is tested and verified the performances through connecting the 110Vac 60Hz utility line. Efficient results are described.

“…A recently proposed converter scheme [4] is shown in Figure 5. The general specifications of the converter are identified in Table 2 and have been calculated according to the considerations that efficiency maximization is easily achieved in a power converter operating with high input voltage and low input current due to sensible reduction of conduction losses.…”

This paper presents an overview of the power converters that are adopted in PhotoVoltaic generation systems in the power range till 20 kW. For this type of renewable energy applications a double trend can be identified according to power conversion systems below few kW and higher than 3-5 kW. The paper deeply analyses both converter configurations also taking into consideration the control aspects connected to the efficient and reliable connection to the grid of such systems.Some experimental results are presented dealing with two prototypes belonging to each of the identified classes of converters.

“…However, these power converters only handle single kind of renewable energy, that is, which cannot deal with multi-input power. Therefore, some researchers propose multi-input converters for solar/wind hybrid power generation system (Sedaghati and Babaei, 2011;Cacciato et al, 2008;Fang and Ma, 2010). Even though these multi-input converters can process hybrid renewable energy, two separated converters in series or in parallel are required.…”

In this study a power converter to process renewable energy is proposed, which can not only process solar energy but deal with wind power. The proposed converter is derived from two series modified forwards to step down voltage for charger system or dc distribution application, so as called Modified-Forward Dual-Input Converter (MFDIC). The MFDIC mainly contains an upper Modified Forward (MF), a lower MF, a common output inductor and a DSP-based system controller. The upper and lower MFs can operate individually or simultaneously to accommodate the variation of atmospheric conditions. Since the MFDIC can process renewable power with interleaved operation, the ripple of output current is suppressed significantly and thus better performance is achieved. In the MFDIC only a common output inductor is needed, instead of two separated inductors, so that the volume of the converter is reduced significantly. To draw maximum power from PV panel and wind turbine, perturb-and-observe method is adopted to achieve the feature of Maximum Power Point Tracking (MPPT). The MFDIC is constructed, designed, analyzed, simulated and tested. Simulations and practical measurements have demonstrated the validity and the feasibility of the proposed dual-input converter.
