Mode 2
In this mode transistor gets turned off by the negative output of PWM current flows through inductance L diode D then divide into two parts one flows through capacitor C and other load. In this condition the magnetic field in the inductor collapses and induces a large voltage across the coil of opposable polarity.
That adds to the input voltage capacitor C will charge through this current and maintain the o/ p voltage when transistor gets turned on for next cycle.
Hexadecimal to Binary Conversion Conversion from hexadecimal to binary is the reverse of this process. Express each hexadecimal digit in four bit binary equivalent
Consider the circuit in Figure (a), which include a controlled source, and find the current in the 5-V source and the voltage across the 5- resistor by using (a) the loop-current
Q. When the J and K inputs of a JKFF are tied to logic 1, this device is known as a divide-by-2 counter. Complete the timing diagram shown in Figure for this counter.
Diac Diac is a device which has di electrode and as its name suggests it works on AC. The cross sectional view of a diac is shown if the four layers are PNPN and PNPN .
area bounded by the curve y=3x(x-2)^2 and the x-axis
