Abstract
It is generally used the boost converter for the welding machine using fuel cell. But this type generates the duplicate loss between boost converter and inverter. As a result, the whole efficiency is lower than conventional inverter arc welder and the cost is expensive due to additional switching device. Therefore, we proposed the inverter rectification type DC-DC converter with boost converter function in fuel cell based TIG welder. The performance of the proposed technique is evaluated on a 1.2kW fuel cell stack based experimental prototype circuit.
