Mode1
When the positive pulse from PWM is applied to the transistor Q shown in figure it gets turned on. In this condition current flows through transistor Q and.
Inductor L. Inductor stores the energy. Diode D is reverse biases in mode 2. If the transistor Q is supplied with negative pulse it gets turned off and inductor reverses its polarity. Now diode D is forward biased with negative polarity of inductor.
What is the use of modem control unit in 8251? The modem control unit handles the modem handshake signals to coordinate the communication among the modem and the USART.
Q. Explain the construction and operation of Enhancement MOSFET? The construction of an N-channel enhancement MOSFET is shown in figure below. Two highly doped N + regions are
There are three types of buses. Address bus: This is used to carry the Address to the memory to get either Instruction or Data. Data bus : This is used to take the Data from
Calculate total resistance among terminal A and B for the circuit below.
Q. Three identical single-phase transformers are to be connected to form a three-phase bank rated at 300 MVA, 230:34.5 kV. For the following configurations, determine the voltage,
Q. Given that a silicon n-channel JFET has V P = 5 V and I DSS = 12 mA, check whether the device is operating in the ohmic or active region when v GS =-3.2 V and i D = 0.5 mA.
Athree-phase, wye-connected, round-rotor, 220- V, 60-Hz, synchronous motor, having a synchronous reactance of 1.27 per phase and negligible armature resistance, is connected in p
There are four basic types of sweeps: (a) Free Running or Recurrent Sweep: in the free running or recurrent sweep, the sawtooth waveform is re
Q. The self and mutual inductances of a machine with two windings are given by L 11 = (1 +sin θ), L 22 = 2(1 + sin θ), and L 12 = L 21 = M = (1-sin θ). Assuming θ = 45°, and le
