ourier analysis shows that the sawtooth waveform of Figure P6.4 can be written as vst (t) = 1 2 sin (2000t) 2 2 sin (4000t) 2 3 sin (6000t) 2 n sin (2000nt) in which n assumes integer values. Use MATLAB to compute and plot the sum through n = 3 for 0 t 2 ms. Repeat for the sum through n = 50. 2 123 t (ms) vst(t) Figure P6.4

Sample Notes EE 212 AC Steady State Power Different types of AC power 1. Instantaneous Power [Watts] 2. Average Power (Active Power, Real Power) [Watts] 3. Reactive Power (Imaginary Power) [VAR] 4. Complex Power [VA] 5. Apparent Power [VA] 6. Power Factor Instantaneous Power p(t) [Watts] p(t) = v(t) i(t); t = time 1. If current i(t) is entering the device then p(t) is positive and the device is absorbing power 2. If current i(t) is leaving the device then p(t) is negative and the device is supplying power
