a. Explanation Given data: ω = 1000 rad / s Formula used: Consider the general expression for inductive impedance. Z L = j ω L (1) Here, L is the Inductor. ω is the angular frequency. Consider the expression of reflected impedance. Z r = ( ω M ) 2 | Z 22 | 2 [ Z 22 * ] (2) Calculation: By using the data in question, draw the circuit as shown in Figure 1. Substitute 180 mH for L and 1000 rad s for ω in equation (1) as follows. Z L 1 = j ( 1000 ) ( 180 m ) = j ( 1000 ) ( 180 × 10 − 3 ) { ∵ 1 m = 1 × 10 − 3 } = j 180 Ω Substitute 500 mH for L and 1000 rad s for ω in equation (1) as follows. Z L 2 = j ( 1000 ) ( 500 m ) = j ( 1000 ) ( 500 × 10 − 3 ) { ∵ 1 m = 1 × 10 − 3 } = j 500 Ω Substitute 100 mH for L and 1000 rad s for ω in equation (1) as follows. Z L = j ( 1000 ) ( 100 m ) = j ( 1000 ) ( 100 × 10 − 3 ) { ∵ 1 m = 1 × 10 − 3 } = j 100 Ω Find X M b. To determine Find the value of impedance Z ab .

Three-Phase Transformers

Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite …

Transformer

Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us hav…

Design a full-wave rectifier power supply using a 9.52:1 transformer. Assume that the outlet is120 V rms @ 60 Hz. Further assume that the diode turn-on voltage V D(on) is 0.7 V. Pick the valueof CL such that vo has a maximum ripple of 1 V p-p . Solve for the average value of vo = Vo (notethat this may be greater than 12 V) and iD(ave) = ID.

Light-emitting diodes (LEDs) are diodes made with III-V compound semiconductor materials such as aluminum gallium arsenide (AlGaAs), aluminum indium gallium phosphide (AlInGaP) or indium gallium nitride (InGaN), instead of silicon. The LEDs emit light when the device is operated under forward bias. LEDs of different colors have different turn-on voltages VD(on). For example: VD(on) : Red: ~ 1.6 V Yellow: ~ 1.7 V Green: ~ 1.8 V Blue: ~ 2.8 V White: ~ 3.8 V (a) Model these five LEDs with a simplified piecewise linear model (b) A rule of thumb is that it takes about 1 mA of current to “light” an LED while ~ 10 mA is needed for it to appear bright. Use the piecewise linear model for the LEDs, for the over-voltage indicator circuit to the right, find the values of Vin which will cause D1 or D2 to light (i.e. when ID1 or ID2 exceeds 1 mA).
