Shown below is a single stage common emitter amplifier with a unipolar dc power supply using an 2N3904 NPN BJT as the active device. It is specified that V+ 40 V, C1 C2CE 100uF, Ro-7.5 k2, REi-5.1kS2, and Ri - 36k52. Design the circuit so that the dc collector current is 2 mA and the magnitude of the small-signal midband voltage gain is 32.3. For the design calculations assume that the base-to- emitter dc voltage drop is 0.65 V, the...

2.3 (20 points) A separately-excited de motor is mechanically coupled to a three-phase, 4-pole, 30-kVA, 460-V, round-rotor synchronous generator. The de motor is connected to a constant 230-V de...
2.3 (20 points) A separately-excited de motor is mechanically coupled to a three-phase, 4-pole, 30-kVA, 460-V, round-rotor synchronous generator. The de motor is connected to a constant 230-V de supply The ac generator is connected to a 460 V, fixed-voltage, fixed-frequency, three-phase supply. The synchronous reactance of the synchronous generator is 513 Ω/phase. The armature resistance of the de motor is 30 m2. The 4-pole de machine is rated 30 kW at 230 V. All unspecified losses are to be...
