6 FAQs about [Inverter high frequency induction]

Can a high frequency inverter be used for induction heating?

Recently, cost effective induction heating (IH) appliances using high frequency inverters have been rapidly developed for utility frequency AC to high-frequency AC power conversion system for consumer power and energy applications.

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.

What is high frequency industrial induction heating?

High frequency industrial induction heating processes typically employ resonant inverters to reach high efficiency at high power levels. Advancements in wide band gap (WBG) device technology has made it feasible to push the possible frequency of these processes into the MHz regime using solid state technology.

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.

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.

What is induction heating machine?

Induction heating machine must not heat the deeper part of the load so much, and heat slighter one intensively. But, because the needed heating depth of each metallic part is different, the required output frequency is also different. The purpose of this inverter is induction heating by high frequency from 160 kHz to 400 kHz.
