Athens High Frequency Power Inverter

What is a high frequency inverter?

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.

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.

Do high-frequency inverters use transformers?

While some of these high-frequency inverters still use transformers, they employ many smaller ones, providing galvanic isolation similar to the bulky single transformer found in low-frequency versions.

Is a new inverter architecture suitable for varying load impedances?

Abstract: This paper presents a new inverter architecture suitable for driving widely varying load impedances at high frequency (HF, 3-30 MHz) and above. We present the underlying theory and design considerations for the proposed architecture along with a physical prototype and efficiency optimizing controller.

Why do high frequency inverters have distortion and harmonic content?

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.

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.
