Open source project of power pre-regulator built to provide all necessary power for the final stage (post-regulator) of a variable bench power supply. The project is initiated by need to replace ...

It’s no surprise that many hardware hackers avoid working with AC, and frankly, we can’t blame them. The potential consequences of making a mistake when working with mains voltages are far greater ...

The StacoVT 1010B is a variable transformer that operates on 120 V and is rated for constant current of 10 A. It is designed to provide a variable output that can be adjusted from 0-117% of the unit’s ...

Abstract: This paper presents an experimental test bench for generating disturbances in a transformer to validate power transformer differential protection methods. The experimental setup uses a 1 kVA ...
