Mode 1 ( 0
By applying a positive output pulse of the pulse width modulator to the transistor Q1 it gets turned on. An input current in flows through Vin Q1 inductor L and then divides into two parts one flows through capacitor C and other through load.
In this mode inductance stores the energy and induced voltage in inductor bunks the input voltage.
Q MCM is the abbreviation for 1 kcmil. problem for a de?nition of cmil.) Data for commercial-base aluminum electrical conductors list a 60-Hz resistance of 0.0880 /km at 75°C for
3-phase 3 wire meter with CT and MD It is exactly such as 3-phase 4 wire meter and works on the similar principle. It is also used in the similar way and under the similar cir
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
Q. Name all the switching schemes used in a digital exchange. How call processing occur? Ans: The basic types of switching systems used are: 1. Stronger Switching System
Q. Explain the working principle of a TRIAC. "Triac" is an abbreviation for three terminal ac switch. 'Tri'-indicates that the device has three terminals and 'ac' indicates tha
Consider an S band (3 GHz) radar with a rotating aperture antenna with a width of 3 m. Suppose the antenna rotates at a rate of one rotation every 10 seconds. Assume the 3 dB bea
