| dc.description.abstract | The use of Universal type motorcycles is very commonly used, both in daily life and in research activities. The universal
motor can be used as a prime mover generator PMSG (Permanent Magnet Synchronous Generator), which in its application
there is an obstacle that is difficult to stabilize the speed due to the influence of changes in the load connected to the PMSG,
this affects the output voltage produced by the generator. In this case, a speed stabilizing system is required to stabilize the
output voltage generated based on the load given to the system. AC Chopper is one of the circuits that can be applied in a
speed control system that serves as an AC-AC voltage regulator that becomes a Universal motor input. Synchronous AC
Chopper is one type of AC Chopper circuit which according to P.Sravan Kumar, in his research entitled Design and
Implementation of AC Chopper (2014) that has been done before has a better performance in terms of efficiency than Basic
AC Chopper. As for this control system, fuzzy logic is flexible and has a tolerance to existing data. Obtained data from the
control that has a settling time of ±15 second and average efficiency of 84.99%. | en_US |
