Grid-tied small wind turbines based on permanent magnet generators are usually operated using a basic converter topology based on a passive rectifier, a boost converter, and an H-bridge inverter. The rotor speed signal is rarely obtained from speed or position sensors in this kind of systems. Model-based estimators are rather used for this purpose relying on electrical magnitudes. Despite its complexity...
Electric machine drive systems have a protection mechanism for momentary power interruption. Generally, when the momentary power interruption is occurred, outputs of a drive system are stopped for the protection. For stable continuous operation, it is sometimes required the restarting strategy which is called as a flying start when the input power is recovered and the rotor is still rotating freely...
