HARDWARE PROTECTIONS INCREASING THE RELIABILITY OF A PROTOTYPE INVERTER WELDER.

The subject of the paper is a presentation of hardware protections, which increase the reliability of a prototype inverter welder. Under certain assumptions, the constructed device may be classified to a group containing objects with a serial reliability structure. As a result, the functionality of the inverter welder is provided, when all components (sub-assemblies) operate correctly. The paper presents the results of simulations, which confirm the essence of using each of the hardware protections. The tests were conducted using the ICAP/4 software by Intusoft.
