This paper is an attempt to provide a dual-source inverter, an intelligent inverter topology that links two isolated DC sources to a single three-phase output through single-stage conversion. The converter is designed to be utilized in hybrid photovoltaic fuel cell systems, among other renewable energy applications.
To demonstrate and validate the suggested inverter's capability to operate at two distinct frequencies simultaneously for Z 1 and Z 2, the switching frequencies for Z 1 and Z 2 were chosen unevenly.
Reference 14 describes a dual-input dual-output inverter with nine switches, allowing each source to supply a separate load. In the topology presented in Ref. 15, the input sources cannot have random voltage or current levels. Two dual-input single-output three-phase inverters are discussed in Refs. 1, 2.
Two dual-input single-output three-phase inverters are discussed in Refs. 1, 2. In the topology developed by Ref. 2, replacing the two inductors of the classic impedance source inverter with two transformers forms a new multi-port inverter. In this inverter, the DC-link voltage is a three-level signal with a specific switching frequency.
The efficiencies of the proposed inverter and those in previous works have been shown in Table 7. In this comparison, it should be considered that the proposed inverter is a single-stage, high voltage gain, microcontroller-based inverter which takes advantage from machine intelligence in its protection procedure.
The topologies presented in Refs. 25, 26, 27, 28, 29, 30, 31, 32, 33 are dual-stage multi-input inverters. These topologies are unique in several ways, including their low number of semiconductors and absence of low-frequency transformers. These features make them well-suited for photovoltaic and grid-connected applications.
