Dynamic analysis of three phase Z-source boost-buck rectifier

Boost-type PWM voltage source rectifiers have gained popularity because they allow the output voltage to be controlled over a wider range. However newly proposed Z-source boost-buck rectifier would allow buck capability with minimal number of switches. This paper deals with dynamic analysis of the Z-source rectifier. The analysis is carried out to determine the transient response and non minimum phase effects. Further discussions are made on how to reduce the non minimum phase effect and increase the system performance. The analysis is supported with simulation results.
