Induction heating technology present in home appliance across the early after which it wealthy in efficiency, economical and atmosphere benefits of growing substantially, with items when using the technology is mature and stable, induction heating technology industry started to build up progressively within the last single-phase 2KW, the three-phase 100KW and above, over a few years, induction heating technology and product programs obtaining a qualitative leap. using the device's internal energy components (eg, rectifier, IGBT modules, thin film capacitors, etc.) progressively popular because of its reliability and stability determine the security and make use of of package existence.

The conventional internal structure of induction heating equipment movement

Induction heating circuit is put into two inside the items available on the market perspective, 30KW or less might be utilized in over half-.30 KW might be used entirely-bridge. 30KW movement with half-perspective, using film capacitors will be the following:

Electricity-LINK :30-40?F (800VDC), multiple discrete capacitors in parallel mode (3-13 a few days)

High resonance: arm 1.2-1.4?F (1600VDC), multiple discrete capacitors in parallel mode (3-14 a few days)

Module using the benefits of film capacitors

a movement inside the primary loop within the bypass process using copper structure, copper thickness is assured however regurgitate to passing ability, low-temperature copper bar. Installation is simple, convenient, fast, efficient and lower the mistake probability.

b the primary circuit only requires two copper strips, rather than yesteryear a considerable PCB, the product material costs and labor costs, and reduced, reliability is enhanced. getting rid of the advantages of PCB plug-in, Container stove, welding along with other processes.

c area of the primary loop control with separate driver, so strong electrical / weak separation to lessen the main resonant circuit within the nick-driven area of the interference within the product after-sales maintenance along with other convenient, multiple-use components, reducing maintenance costs .

d As capacitors are modular forms package, available aluminum warmth, movement may be hermetically sealed solved the fumes, moisture, roaches, dust along with metals towards the movement's internal problems, enhanced product reliability and existence.

e with a few discrete capacitors in parallel to make a single module, to resolve the discrete capacitor within the uneven flow, partial pressure of inequality along with other concerns, shorten the area however circuit line, lowering the road inductance across the energy distribution areas of the impact.

Actual standby time using the capacitor module

To look for the aluminum cooling module internal temperature the resonant capacitor, the capacitor module in creating samples into an internal NTC thermistor. Anyone to make the most of two * .8?F/1600VDC modules based in the half-bridge circuit 15KW induction oven.

Inside the measured data proven the resonant capacitor module within the aging room at 25 ? and 40 ?, full energy about half an hour at the office, film capacitor internal temperature to stabilize, with the enhanced working several hrs, the temperature remains stable lower.

Current Electricity-LINK capacitor module (MKP-LA) and resonant capacitor module (MKPH-RA) through numerous co-operation with mass use, the Division remains creating e-mail within the series capacitor modules effectively requested national patents.

Summary

IGBT might be created through the type of modules form just one tube, cooling effect, over-current capacity during this Division Reference IGBT internal cooling structure, developed the dwelling within the capacitor with aluminum cooling module, present in induction heating products. After more than co-unit amounts to be used, offers a great market using 2010.

While using the induction heating equipment market demand is continually increase, the product more competitive. Companies to enhance their items, business, must invest human and material assets, that old product updates, technology upgrades, to be capable of boost their competitive pressure
