Single-phase full-wave diode rectifier
Single-phase full-wave diode rectifier Single-phase diode rectifier, converting ac signal into a dc voltage, exist in two types - half-wave and full-wave one. Half-wave…
Three-phase diode rectifier
Three-phase diode rectifier convert AC balanced signal into stable DC signal where power output is higher than 15kW. Three-phase diode rectifiers can be two…
Rectifiers for filtering purposes
Rectifiers are used for creating the smooth DC output voltage, for this purpose there is usually filters are used in rectifiers. This systems can…
Line-commutated single-phase half-wave rectifier
This post describes the topic: "What is line-commutated single-phase half-wave rectifiier". Last posts described single-phase rectifier using diodes. Another configuration of line-commutated single-phase half-wave…
Line-commutated single-phase bridge rectifier
This post answers the question "What is line-commutated single-phase bridge rectifier?". Bridge rectifier can be fully controlled with four thyristors and half-controlled with two…
Line-commutated three-phase rectifier
This post answers the question: "What is line-commutated three-phase rectifier?". As we know from previous post, these rectifiers are used to convert a fixed…
Maxwell’s magnetic theory
Still a question that has to be answered is why conductivity electrons are moving in the magnetic field in the conducting circuit. (Figure 37).…
Shift current and Maxwell equations
Variable magnetic fields create a vortex electric field in the conductor, which leads to the electric current appearance in the conductor. Let’s consider two…
Enhancement MOSFETs
FET transistors are working differently than BJT transistors. In FET width of conducting channel is varied by applying of external electric field. They operate…
