Diodes Types and Half-Wave Rectifier (controlled and uncontrolled) ReportAyad Saadi
Three-phase half wave uncontrolled rectifier requires three diodes, each connected to a phase. The three-phase rectifier circuit suffers from a high amount of harmonic distortion on both DC and AC connections. There are three distinct pulses per cycle on the DC side output voltage. A three phas...
The circuit diagram of the controlled half-wave rectifier is similar to the uncontrolled rectifier except for the fact that the uncontrolled diode is replaced by a controlled SCR. Fig. 4.42 shows the circuit of the controlled half-wave rectifier. The load at the output is resistive. When the ...
A half wave rectifier is the simplest form of rectifier available. We will look at a complete half wave rectifier circuit later – but let’s first understand exactly what this type of rectifier is doing. The diagram below illustrates the basic principle of a half-wave rectifier. When a stan...

The fault current continuously charges the submodule capacitors through the freewheeling diode, and the MMC acts as an uncontrolled rectifier bridge. Figure 10 shows the fault current path after the submodule locked. FIGURE 10 Open in figure viewerPowerPoint Fault current paths of recombined half-...
