Second Quadrant or Class B Chopper
Class B chopper is shown in figure in this type of chopper load must contain a dc source E ( may be battery or a DC motor) and inductances the operation of classes B chopper as follows.
Mode I
When SW is on V0 = 0 but current will be flowing through inductance L and chopper SW due to E as shown in figure in this mode inductance L stores energy.
Figure shown the polarity of inductance and direction of load current. It is clear from this figure that this polarity's same as in directed but the current is flowing in reverse direction. Hence is negative.
Mode II
When SW is off V0= { E+ L di0/dt} exceeds the Vs therefore diode D becomes forward biased and current flow load to source through diode D. Again the load voltage is positive but current is in negative direction. In this mode inductance releases energy and the polarity is shown in figure.
Hence the Vo -I0 characteristics is shown in figure that lie in second quadrant.
Given the INPUT: • An array of 64-bit unsigned integer elements stored in the memory starting at a known location SOURCE. • The size of the array (i.e., number of elements) stored
The output port of the one-port is defined by terminals A and B. Given: R 1 = 10 k_, R 2 = 20 k_, R 3 = 10 k_, and R 4 = 10 k_ V 1 = 20 V and I1 = 0.8 mA a) Find the T
Explain Hall Effect. Hall Effect: If a current carrying conductor is placed in a magnetic field, a voltage is produced that acts in the perpendicular direction to the current
Condition Return Similar to conditional jump and call instructions there are conditional return instructions also based on various flags.
In continuation of Part-B, the student is required to configure an engine management system for the proposed engine and produce a report including the following: A preamble
I need I circuit that calculates f(n) = 2^2^n, where n is a 4bit number. I tried with a decoder but unsuccessfully.
For Parity Flag PRE ( Return on Parity Even) and RPO ( Return on Parity Odd) Instructions RPE returns from the subroutine to the calling program if parity flag is not s
How the interrupts can be masked/unmasked in 8086? The 8086 interrupt priorities are concerned; software interrupts have the highest priority, followed by NMI followed by INTR.
