In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
A half-wave cycloconverter is used to integrate the microinverter to the grid at the secondary side. By using a half-wave cyclo-converter, the number of switches in the secondary side can be reduced by half compared to a full-wave cycloconverter. This is expected to result in reduced switching and conduction losses in the overall inverter.
A microinverter with full-bridge inverter and a half-wave cycloconverter is proposed in . Frequency modulation is used as the power control method of this inverter. Hence, it has some drawbacks such as a wide and unpredictable noise spectrum, more complex filtering of the output voltage ripple, and poor utilization of magnetic components .
The full-bridge inverter is used as the primary-side inverter of the microinverter due to its higher voltage gain compared to the half-bridge inverter, although the number of switches in the full-bridge circuit is twice that of the half-bridge.
Full-bridge inverter and half-wave cycloconverter topologies are selected because together they reduce the required transformer turns ratio (e.g., as compared to using a half-bridge inverter or a full-wave cycloconverter), thus improving achievable efficiency.
The soft-switching operation of the full-bridge half-wave cycloconverter is analyzed using the derived resonant current equation for the three stepped full-bridge output voltage and the half-wave cycloconverter input voltage.
