What is a high frequency variable load inverter?

ut Pmax VINmax13:56MHz21:31kW375VIV. CONTROL SCHEMEA. Control ChallengesIn Section II the high frequency variable load inverter was modeled with each constituent inverter as an ideal voltage source that could drive any resistiv / inductive load, only sub-ject to maximum output voltage and current limits. However, real inverters h

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.

What is the purpose of a high frequency inverter?

The purpose of this inverter is induction heating by high frequency from 160 kHz to 400 kHz. The heated object of the inverter is a columnar metal with a small radius. Inverter must output higher frequency to heat only the surface of load. for high frequency inverter, and shows the experiment result.

How a resonant inverter is used for metalworking?

Resonant inverter used for metalworking by the induction heating. In induction heating, high frequency can heat the shallow point, and low frequency can heat the deep point. So when heated depth is replaced, the frequency that inverter must output is different. It is necessary for the inverter to output two or more frequencies.

What frequency should a resonant inverter output?

This inverter is requested to output frequency from 160kHz to 400kHz. Resonant inverter used for metalworking by the induction heating. In induction heating, high frequency can heat the shallow point, and low frequency can heat the deep point. So when heated depth is replaced, the frequency that inverter must output is different.

Why do inverters need to change the output frequency for induction heating?

Induction heating has characteristics that lower and higher frequency heats the deeper and slighter part of the load respectively. So the inverter for induction heating must change the output frequency into the best value. For example, the metal can become harder by heat-treat "Harden" being done.
