9.6 Consider the ideal dc-to-ac inverter shown in Fig. P9.6. Assume Si/S4 and S2/S3 are switched...
4-13 In the balanced three-phase dc-ac inverter shown in Fig. 4-12b, the phase-A average output voltage is van (t)-40.75 sin(at), where V-300V and a-2π x45 rad /s. The inductance L in each phase is 5 mH. The ac-motor internal voltage in phase A can be represented as et)-106.14sin(ot-6.6°)V, assuming this internal voltage to be purely sinusoidal.

2. Figure 2 shows a 6-pulse thyristor rectifier feeding a DC static load an operating at steady-state. The ac input power supply is a symmetric set of three-phase voltages forming a direct sequence, having rms line-to-line voltage of Vuns equal to 415 V and angular frequency ω equal to 100π rad/s. The load is sufficiently inductive to smooth out the load current i(t), i.e. i 1, where I is a constant. a. Derive the mathematical expression of the average DC...
