Electronic Circuit for the control stage of Welding Machines, ARC, Portable type inverter working at more than 1000 meters above sea level.

摘要

Referring to an electronic circuit for the control stage of a welding machine with Arc type MOSFET inverter Technology, High Performance and compact size, which comprises a control Circuit and a PWM MOSFET Driving Circuit; MOSFET; a Protection Circuit sobrecarg Ace, Short Circuit and overheating.There is a device used in Industry as a control Circuit of the welding machines are manufactured for the locksmith work to more than 1000 meters above sea level, therefore we need to design a special Circuit which works efficiently in the category referred to in high areas Andean.Consequently, the field of the manufacture of Welding Machine DC Type inverter, manufactured for the locksmith sector where the average working current is 140 amperes with a duty cycle of 90 and 120 AMPS at 100% duty cycle, then make an analytical Comparative Analysis of working parameters.We conclude that it is necessary to Design an electronic circuit for the control stage and the MOSFET transistor type used in the design of electronic circuit for switching Voltage not exceeding 300 volts Continuous Output Current up to 200 Amps. In addition, for Rapid Response to frequencies lower than 20 kHz.
