摘要:This paper presents a literature survey on adjustable-speed drives (ASD) systems which are based on the different types of inverter topologies (namely voltage source inverter and current source inverter fed ASD system). It can overcome limitations of previous speed drive systems. The proposed inverters and ASD system can operate at wide range load (even no-load) with small inductor which is very suitable for ASD system, simplify the controller design, increase the inverter modulation index M, thus, decreases the ripple current by changing the magnitude and distribution of the harmonics and further decreases the iron loss of the motor. The operation of voltage source inverter, current source inverter have been described in detail along with the PWM technique.Authors strongly believe that this survey article will be very much useful to the researchers for finding out the relevant references in the field of improvement of speed control of drives and reduction of harmonics in three phase induction motor by PWM-techniques.
