Diode rectifiers with inductive and capacitive on the dc side. Both single and three-phase systems are studied. Diode rectifiers are very commonly used and are the cause of significant power quality problems. This experiment investigates operation of diode rectifiers with inductive and capacitive filters connected to both single and three-phase ac lines and the impact on utility supply. Thyristor rectifier operation under varying load condition.
Interest includes line currents and harmonics.
This experiment investigates thyristor rectifier operation under varying load conditions. Parameters of interest include operation in motoring and regenerative modes, firing angle control, input line current waveforms, reactive power needs and harmonics. Interactions between converters, ac side filters and the ac source. Passive filters are studied. This experiment exposes students to interactions between the converter, ac side filters and the ac line.
