6 Frequently Asked Questions about “Is the inverter s high-frequency electromagnetic wave good ”
What is a 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.
What are the advantages 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.
Are power frequency inverters good?
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.
What is the difference between high frequency and low frequency inverters?
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.
Why are frequency drive inverters more efficient?
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.
How do high frequency power inverters convert DC to AC?
High frequency power inverters typically convert the DC to AC by driving the transistors at a much higher frequency from 50 Kilo Hz to a few million Hz. Low frequency inverter circuit diagram
