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.
Self Inductance If a current is passed through a coil, it creates a flux within the coil. Any attempt to change this flux will create a back emf that acts to oppose the chang

Q. Draw and explain diode clipping circuit ? A diode clipping circuit can be used to limit the voltage swing of a signal. Clipper circuits are used to clip a portion of the w
Q. Sampling of digital communication systems? Sampling of an analog signal makes it discrete in time. A bandlimited signal can be recovered exactly from its samples, taken peri
HOW ARE FLIP-FLOPS USED IN BINARY COUNTERS
A flyback converter is to be designed so that it operates in continuous "current" (flux) mode with a duty cycle of D = 0.45 when input voltage V s = 48 V, output voltage V o = 30
