Abstract :
The Z-source rectifier is a recently proposed converter topology which has a unique X-shaped impedance network on its DC side. In the process of designing the controller circuits for the Z-source rectifier, knowledge of transfer functions relating the dynamics of various variables is essential. This paper deals with the modeling of Z-source rectifier with the intent of developing a robust controller. Modelling is carried out using a set of state equations obtained by state space averaging the circuit equations in shoot through and non shoot through states of the rectifier. The derived model is verified with both simulation and experimental results.
