Document Summary

Ele847 week 10 (try problems 4. 1-4. 5: square wave operation (v/f control) (project part a) Stator voltage and frequency (i. e. inverter output and voltage: pi regulator is used to optimize system dynamic performance. Compensation voltage at low frequencies compv (cid:131) to compensate the air-gap flux vk - v/f coefficient: ramp function generator sf sf sf. 5g t t t: ramp function generator use simulink ramp block + a limiter, voltage detector. Q: transformer functions: isolation isolate the control circuit from the power circuit, to reduce the voltage level: C: filter rc low passive filter or op-amp based active low pass filter. 2r (no pwm: use a voltage divider fv. No voltage isolation between control and power circuits: pwm operation (v/f control) (project part b) dr. 3 dc dcv fv , s s sf dm fv sv vk sf. A: im (5th) +pi (1st) + dc link filter (1st) + voltage detector (1st order filter) = 8th order system.
