The difference between medium frequency and high frequency inverter

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.

Low frequency inverters generally have a longer lifespan than high frequency inverters due to their more durable components. In conclusion, low frequency and high frequency inverters have their unique features and benefits. Low frequency inverters are ideal for applications that require high power output and can handle heavy-duty appliances.

Due to the use of high-frequency switching technology, high-frequency inverters have the advantages of small size, lightweight, and high efficiency, but they also have the problem of relatively poor output waveform quality.

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.

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.

Due to factors such as the nonlinear characteristics of the high-frequency switching tube and the parasitic parameters of the high-frequency transformer, the output waveform of the high frequency inverter may have certain distortion and harmonic content.
