| Abstract |
This paper presents the power conversion system for TIG-welder using the fuel cell stack. Generally, power supply for TIG-welder uses the front-ended diode bridge rectifier by common AC power source. In this case, power supply of TIG-welder increases in volume because of using bulky capacitor and diode-rectifier. Also, input current includes ripple and harmonics. Moreover, TIG-welder will be demand the power supply with lightweight and easy movement in the areas like as the islands and mountainous areas or the special environment are not use common AC power source. Thus, input power of the power conversion system for TIG-welder is used PEMFC(Polymer Electrolyte Membrane Fuel Cell), and the power conversion system is comprised of full-bridge converter with function of boost converter and inverter welding source, in this paper. The proposed power conversion system which is power supply for TIG-welder was verified by computer simulations and experiments. |
