The system Ẋ = AX + Bu with A = ≤ft[ {*20c - 1&2\\ 0&2 } ], B = ≤ft[ {*20c 0\\ 1 } ] is

Assuming that the diodes in the given circuit are ideal, the voltage V0 is ______ volts.

The power electronic converter shown in the figure has a single-pole double throw switch. The pole P of the switch is connected alternatively to throws A and B. The converter shown is a

The following figure shows a composite switch consisting of a power transistor (BJT) in series with a diode. Assuming that the transistor switch and the diode are ideal, the I-V characteristic of the composite switch is

The fully controlled thyristor converter in the figure is fed from a single-phase source. When the firing angle is 0°, the dc output of the conveter is 300 V. What will be the output voltage for a firing angle of 60°, assuming continuous conduction ?
