Question

Problem: Consider the three-phase Y-connected circuit that we analyzed in the lectures. Suppose $r_s = 1$, $L_s = 0.8$ mH, and $M = -0.2$ mH. At $t = 0$, the circuit is energized by a voltage source with $e_a = 10$ V, $e_b = 15$ V, and $e_c = -19$ V (all dc). Derive an expression for the neutral wire current as a function of time, and sketch this waveform.

Step 1

First, we need to find the total impedance of the circuit. The impedance of the resistor is simply r = 1Ω. The impedance of the inductor can be calculated using the formula ZL = jωL, where j is the imaginary unit and ω is the angular frequency. In this case, ω = 0 Show more…
