Myth vs reality: higher switching frequency in PV inverters
Stop guessing about PV inverter specs. This guide debunks myths on high switching frequency, revealing the truth about efficiency, size, and reliability for your solar system.
High frequency inverter: High frequency inverters use high-frequency switching technology to chop DC power at high frequency through high-frequency switching tubes (such as IGBT, MOSFET, etc.), and then convert high-frequency pulses into stable alternating current through high-frequency transformers and filter circuits.
Volume and weight: Since high frequency inverters use high-frequency switching technology and compact circuit design, their size and weight are usually much smaller than power frequency inverters. This gives high frequency inverters significant advantages in mobile power supplies, aerospace, electric vehicles, and other fields.
In contrast, power frequency inverters can maintain high efficiency and stability under heavy load or overload. Output waveform quality: The output waveform quality of power frequency inverters is usually better than that of high frequency inverters.
Efficiency and energy consumption: Because frequency drive inverters use high-frequency switching technology, their switching losses and iron losses are relatively small, so their efficiency is usually higher than that of power frequency inverters.
