IGBT in Plasma Cutters – Spanish

La definición del corte de plasma es cortar materiales electrico-conductivos diferentes (mayormente metales como el acero, aluminio, latón y cobre) de varias tamaños y dimensiones usando un jet de plasma, la antorcha de plasma es lo suficientemente caliente para separar el material que esta siendo cortado y se mueve lo suficientemente rápido para apartar los excesos innecesarios del rustico del corte limpio que esta produciendo, Los IGBT son usados en la tecnología con corte de plasma para mejorar la eficiencia comercial de sus cortadores.

 

Los cortadores de plasma IGBT se emplean mejor en ambientes profesionales como constructoras industriales, fabricas, reparaciones y restauraciones de automóviles son solo algunos de los usos mayoritarios para estos implementos, la razón principal detrás de su variado y solicitado uso es que es que los cortadores de plasma IGHBT tienen un método diferente de empezar el modo piloto. Muchos cortadores de plasma para metal IGBT tienen la mas alta tecnología en cuanto a alta frecuencia y circuitos de alto voltaje, solo para el proceso inicial, donde la antorcha empieza su función sin tocar la pieza en la que trabaja, creando asi un trabajo impecable y preciso.

 

IGBT: Es el transistor bipolar de puerta aislada es un dispositivo semiconductor que generalmente se aplica como interruptor controlado en circuitos de electrónica de potencia.

El MOSFET: es el transistor de efecto de campo metal-óxido-semiconductor o MOSFET es un transistor utilizado para amplificar o conmutar señales electrónicas:

Este ha sido un tema de debate por mucho tiempo, desde que la tecnología MOSFET llego en los años 80, sin embargo, el IGBT ha probado su superioridad a la hora de trabajar bajo periodos mas rigurosos y por mas duración de tiempo en un ciclo especifico, el IGBT ofrece también una mayor tolerancia al calor que el MOSFET, es por esto que IGBT debería ser siempre su primera opción.

Use of IGBT in Plasma Cutting and Welding

The definition of plasma cutting is cutting different electrically conductive materials (mainly metals such as steel, aluminum, brass and copper) of various sizes and breadth using a plasma jet. This torch of plasma is hot enough to thaw the material which is being cut and it moves fast to blow the ragged part away from the present cut. Insulated Gate Bipolar Transistors (IGBTs) are used in plasma cutting technology to improve the efficiency of commercial plasma cutting equipments.

 

IGBT based plasma cutters suit better in professional environments such as industrial constructions, salvage and scrapping operations, fabrication and welding shops, automobile repair and restorations. The main reason behind this is IGBT plasma cutters take up a different method to start the pilot arc. Significant numbers of IGBT plasma metal cutters often deploy high frequency starting technology and high voltage circuit for the starting process only where the torch enables a constant arc without touching the work piece.

 

IGBT vs the MOSFET (Metal Oxide Semi-conductor Field Effect Transistor) has been an agitated topic ever since the IGBT technology came into being in the 1980’s. IGBT technology for welding applications has clearly proved to more effectively handle the rigorous demands the high duty cycles welders as it offers higher voltage capacities and heat tolerances than the earlier MOSFETs.

IGBT in Arc and Tube Welding

The usual usages of Arc and tube welding machines are to build and repair of the infrastructure in industrial environment. Welding power supplies are needed for creating an electric arc between an electrode and the foundation material to soften the metals at the welding point. Either DC or AC current with consumable or non-consumable electrodes may be used to generate the arc. Some type of inert or semi-inert gas is used sometimes to protect the welding region. Low capital and running cost are the main reasons behind the popularity of Arc welding. In case of arc welding, the voltage is involved right away with the length of the arc, and the current is involved with the sum of heat input with typical currents of 50 to 500 amps is conditional on the size of weld. For arc welding with less voltages and large currents, a soft switching PWM DC-DC power converter with IGBT switches in the elementary side of a high frequency transformer is considered to be the most compatible topology for the welding power supply. Power losses in the IGBTs are lessened by applying soft switching leading to a volume reduction of 59% and weight reduction of 47% in comparison to the hard-switching technique. Because of the operation at 40-kHz, progressive welding performance is enhanced in comparison to the 13-kHz with hard-switching.

 

An induction heating technique with high power and operating frequency is required by tube welding and quenching applications. For lessening switching loss, a multiple frequency converter circuit uses IGBTs with zero-current-switching (ZCS). For this reason, the operating frequency can be increased effortlessly up to 250-kHz which is adequate for quenching and arc welding.
