6. A current-source-type four-switch inverter based on switch multiplexing technique can be used to reduce the input low-frequency current ripple as well as DC capacitor requirement. It is proved to be input-ripple-free and more efficient, and its size is much smaller because the DC capacitor size can be reduced significantly.
We are moving towards solar power but it is still a developing technology with less than one per cent of consumers having access to it. So inverters are here to stay for at least next 50 years, strengthening the case for their improvement to make these more efficient.
