A welding machine is an electrical device which is able to generate a very high current at relatively low DC voltages. This high current output can be suitably used for creating the intended welding arcs and welding joints. The welding joint is created by fusing the welding rod on the joint area through a high […]

How to Design a Solar Inverter Circuit
When a DC to AC inverter is operated through a solar panel, it is called a solar inverter. The solar panel power is either directly used for operating the inverter or it’s used for charging the inverter battery. In both the case the inverter works without depending on mains utility grid power. Designing a solar […]
Grid-tie Inverter (GTI) Circuit Using SCR
Grid-tie inverter concepts may appear to be complex due to the many criticalities involved with them, however with some intelligent thinking it could be actually implemented using primitive technologies. One of the ideas has been explored here. Introduction The discussed idea of a simple grid-tie inverter circuit was suggested by one of the interested readers […]
