In the conversion of AC to DC power, the typical operating frequency is that of the AC line or multiples thereof. AC-DC rectifiers with high-frequency controlled regulation leverage this type of control to enhance their performance. Indeed, if the operating frequency is increased to the order of thousands of Hertz, power circuits can be downsized. […]

AC-DC rectifier unit are the most crucial components of the power system for telecommunications. They are responsible for converting alternating current into direct current for use by telecommunications equipment. This energy must be stable and regulated to ensure that all its parameters remain constant despite fluctuations in the electrical grid and loads. This stability is […]

AC-DC rectifiers are widely used in power systems for telecommunications, converting AC energy into DC. In this post titled Controlled and uncontrolled ac-dc rectifiers, we will explore the two types of conversion. This conversion, technically termed wave rectification, involves eliminating the alternation in the alternating current signal and delivering a linear signal of constant value. […]

After ampacity, or the maximum current-carrying capacity of a conductor in amperes, voltage drop is the most critical parameter when selecting wiring. Therefore, here we present how to calculate voltage drop in DC electrical conductors. This phenomenon involves the power loss that occurs in the conductor due to its electrical resistance. As a result, the […]
