High frequency inverter and low frequency inverter are complimentary and separate in their functions in the power management systems. High frequency inverters are meant for dc-ac conversion at high frequencies, thus their small size and greater efficiency makes them useful in renewable energy systems such as solar and wind energy. On the other hand, low frequency inverters use low switching frequency and are preferable for heavy industrial uses requiring robustness. Do not believe that two distinctions of these inverters are differences in various countries inverters where their business can enhance the energy solutions towards efficient and increased productivity.
