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 is the difference between industrial and high-frequency inverters?
Industrial frequency inverters have high stability and are suitable for high-demand occasions; high-frequency inverters are small in size and high in efficiency, and are suitable for limited space. The selection needs to be considered comprehensively.
What are common high-frequency inverter circuit configurations?
Common high-frequency inverter circuit configurations include: Key design factors for high-frequency inverters: Switching frequency – Higher frequency allows smaller filter components but increases losses. Optimize based on tradeoffs. Filter components – Smaller inductors and capacitors possible at high frequencies. Balance size versus performance.
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 high-frequency inverters a good choice?
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.
Are high-frequency inverters suitable for space-constrained applications?
The operating frequency of high-frequency inverters has been significantly improved, usually reaching several thousand hertz or even higher. The high-frequency design makes high-frequency inverters superior in terms of volume, weight and conversion efficiency, and is suitable for space-constrained application scenarios. 1.
