A performance analysis of closed loop speed control for ZSI&HPZSI IMD

The way to integrate the traditional and renewable sources for development of Electrical technology. Z-source inverter topologies can be implemented in renewable operation like solar system. A new closed loop speed control of an induction motor fed by a high performance Z-source inverter and traditional Z-source inverter based on V/F control. A V/F control is based PWM voltage modulation and PWM technique is used for Z-source inverter. A PI dual loop controller (i.e. current and voltage controller) is used to control the shoot-through state of Z-source capacitor voltage error.
