Buck Converter
In buck converters the output voltage is always less than the input voltage. The basic circuit of buck converter is shown in figure. The operation of this circuit can be divided into two modes. In mode transistor Q is turned on at t=0 to t=t this time interval from 0 to t1 is ton. In mode 2 transistor is turned off at t=t to ti=t2 and this time interval t2- t1is Toff.
For the network shown in Figure, find the current delivered by the 10-V source and the voltage across the 3- resistor by means of mesh-current analysis.
Q. A 60-Hz, six-pole, wye-connected, three-phase induction motor, with the parameters R 1 = R 2 = 0.025 and Xl 1 = Xl 2 = 0.125 , is controlled by variable-frequency control
