Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000.
This solution implements an isolated DC-DC stage with the MPPT algorithm, to make use of the full capacity of the solar panel. The solar inverter maintains its input voltage at the reference set point generated by the MPPT algorithm, and delivers power to a downstream DC-AC inverter when connected across its output.
This approach is well matched to the requirements of module integrated converters for solar photovoltaic (PV) applications. The topology is based on a series resonant inverter, a high frequency transformer, and a novel half-wave cycloconverter.
The solution design includes bidirectional 3-phase DC-AC algorithms, and the maximum power point tracking (MPPT) DC-DC algorithm for solar panel control. The solar inverter has gained more and more attention in recent years. The solar inverter gets the solar energy input, then it feeds the solar energy to the grid.
The DC-DC stage is responsible to maintain MPPT of the panel and the inverter is responsible for the synchronization with the grid and feeding current into the grid.

CONCLUSION This paper introduces a microinverter for single-phase PV applications that is suitable for conversion from low-voltage (25-40 V) DC to high voltage AC (e.g. 240 Vrms AC). The topology is based on a full-bridge series resonant inverter, a high-frequency transformer, and a novel half-wave cyclo-converter.
A typical inverter comprises of a full bridge that is constructed with four switches that are modulated using pulse width modulation (PWM) and an output filter for the high-frequency switching of the bridge, as shown in Figure 1. An inductor capacitor (LCL) output filter is used on this reference design.
