Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these pole…

2. a) Given the circuit shown below in figure P2, compute the inductor current, iL(t), for t≥ 0 utilizing the generalized equation method presented in lecture. Assume the switch shown in figure P2 is ideal and opens in zero time at t=0[s]. The current and voltage conventions shown must be used in the analysis to receive any credit. b) Use your answer to part 2(a) above and the relationship between the inductor current, iL(t), and the inductor voltage, VL(t), shown below in equation P2 to compute VL(t) for t≥0. Equation P2: V(t) = L di(t) dt + Vs = 100[V] t=0 I₁ R₁ = 100[2] w V₁ A ||iz(t) V2(t) R₂ = 200[2] ↓iL(t) | iz(t) V3(t) R3 = 200[2] VL(t) L = 1[H] B Figure P2

s+10 H(s) = 10. 1. Rewrite the network function as a product of recognizable 1st order responses. 2. Name each response (gain, LP, HP, diff., integrator, augmented diff.) and provide a numeric value for the respective critical frequency. • Clue: Integrators and differentiators are uniquely specified by their "unity gain” frequency the frequency at which the magnitude response becomes 1 or 1 dB. 3. Sketch the corresponding magnitude response on a dB-per-decade (log-log) scale.
