Phase Controlled Rectifiers
MATLAB is installed on EIT's Remote Lab 9
Theoretical Background:
AC/DC converters, also known as rectifiers, are one of the most common power electronic circuits, generally used for converting ac electric energy from the Power System to its dc equivalent. These circuits employ diodes as the switching elements and can be classified into half-wave, full-wave and three phase rectifiers. Contrary to these ordinary rectifiers (better named as uncontrolled rectifiers), phase controlled rectifiers employ controlled switches e.g. SCR for their implementation. Using this strategy allows us to control the time for which the circuit conducts in any or both the ac half cycles.
A. Single Phase Rectification
1. Simulate these circuits (using parameter values given in the lab) and capture the snapshots of the source voltage, output voltage, output current and positive & negative gate pulse.
2. Compare the results of R and RL load.
B. Three Phase Rectification
1. Simulate this model and take screenshots Capture snapshots of source voltage, output voltage, output current and positive & negative gate pulse.
2. Compare the results of R and RL load.
