This paper presents an ac-dc-ac reversible nine-phase machine drive system. The grid side converter is composed of Y-connected single-phase bridges. As the machine is composed of three three-phase groups, a three-leg converters are connected separately to each group. The topology does not make use of input isolation transformers and reduces the power processed by converter switches when compared to...
In this paper the output of the single phase wind generator, common for low power application, is converted efficiently into a three phase power. A control system for impedance(z)-source inverter is designed suitable for this wind power conversion. The variable output of wind generator due to unpredictable variation in wind speed, is suitably controlled through a closed loop system through boost-capability...
Impedance (Z)-source inverter can provide stable output by smooth controlling of shoot-through duty cycle of any of the traditional PWM bridge inverters. In this paper a control system for impedance-source inverter is designed suitable for wind power conversion system. The main challenge in wind power system to maintain a constant voltage at the output with unpredictable variation in wind speed, is...
