Grade evaluation method :
Regular exams (70%, average score of 2 exams) + Mini tests and Portfolio (30%)."
Notice:
"Precautions on the enrollment :
This is a ""class that requires study outside of class hours"". Classes are offered for 15 hours per credit, but 30 credit hours are required in addition to this. Follow the instructions of your instructor for these extra studies.
Course advice :
In order to understand this lecture, students must understand accurately the operation of three-phase AC in a rectifier circuit and the characteristics of L and C in a chopper inverter.
Foundational subjects: Fundamentals of Integrated Science and Technology (1st year), Basic Electric (2nd), Electrical Apparatus Ⅰ,II (2nd, 3rd), Electronic Circuits Ⅰ (3rd), Electric CircuitsⅠ, II (3rd, 4th)
Related subjects: Electric Power Transmission and Distribution (4th year), Electrical and Electronic Materials (5th)
Attendance advice :
To ensure an understanding three-phase signal, you may review Electrical ApparatusⅡ. Questions are welcome. This subject is useful for the Third Class Chief Electrical Engineer Examination (machinery, etc.). 25 minutes after the start of class is considered late and 3 late arrivals will result in 1 absence."
