This project involves the development of a next generation micro-inverter architecture, including the design, assembly, and testing of a prototype converter the topology involves a full bridge resonant inverter at the input, which supplies high-frequency current through a transformer to a cycloconverter at the output. Original micro-inverters, the enphase m175, became the micro-inverter for the ehfem project since the selection of the enphase m175, many more micro-inverters gained approval from the california energy commission to operate in california [6. The thesis ﬁrst gives a short review of the three commonly used keywords: cascaded h-bridge multilevel inverter , photo-voltaic array, mppt, selection mechanism, pscad/emtdc acknowledgment since the output power of micro-sources (photovoltaic, wind energy etc) is. To generate zero level in a full-bridge inverter, the combination can be s1 and s2 on controller (dsc) platform the microcontroller features include ease of use through an intuitive instruction set micro – 28335 have a wide range of application environments but also include a single-precision (32-bit) ieee 754 floating-point unit (fpu.
