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.
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.
Output waveform quality: The output waveform quality of power frequency inverters is usually better than that of high frequency inverters. Since the power frequency inverter uses traditional components such as transformers and inductors to transform voltage and current, its output waveform is closer to a sine wave and has lower harmonic content.
Here is the major difference of them: Thanks to the heavy-duty transformer, low frequency inverters have much higher peak power capacity and reliability. The transformer handles higher power spikes with longer duration than high-frequency inverters when it comes to driving inductive loads such as electric motor, pump, compressor, air conditioners.
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.
