Answer all questions below and test your knowledge.

1
Consider a DC circuit with a 12 V source, a 2 kΩ resistor in series, then a parallel combination of a 6 kΩ resistor and a 3 kΩ resistor, with the 3 kΩ resistor also in series with a 4 kΩ load resistor. The 4 kΩ load is to be analyzed. Determine the Thévenin equivalent voltage and resistance seen by the 4 kΩ load resistor.
Question 1
2
In the frequency-domain design of a switching converter feedback loop, a Type 2 compensator is often used. Which pole-zero configuration correctly defines a Type 2 compensator?
Question 2
3
Field-oriented control of AC induction motors relies on the dq0 transformation. What is the primary purpose of this transformation in this context?
Question 3
4
A series RLC circuit has L = 0.1 H and C = 10 µF. What value of R will yield critical damping?
Question 4
5
In modern grid-tied photovoltaic systems, phase-locked loops (PLLs) are essential for inverter control. What is their primary function in this application?
Question 5
6
Estimate the skin depth in aluminum for a 60 Hz AC current. Use typical values: resistivity of aluminum = 2.82 × 10⁻⁸ Ω·m, relative permeability ≈ 1, permeability of free space = 4π × 10⁻⁷ H/m.
