A step down chopper is to be used to supply power from 600 overhead wire to commutator motor on a trolley bus . The motor may be modeled as a generated direct voltage in series with a resistance of .2? and inductance of 25mH. The frequency of the chopper is set at 500 Hz.1-When the bus is stopped , what should be the ON time of the chopper to provide a motor current of 150 A ?2-What is maximum possible generated voltage of the motor for which a current of 150 A can be supplied ?3-What is the average value of the supply current for the conditions of 1 and 2
Calculate the thermal-equilibrium electron and hole concentrations in a compensated p-type semiconductor. Consider a silicon semiconductor at T=300K in which Na = 10e16 cm-3 and Nd=3x1015 cm-3. Assume ni = 1.5 x1010 cm-3.
Calculate (i) the parallel capacitance C1 that would be required to change the power factor of the total load on the supply to 0.80 lagging and (ii) find the value of the supply current at this power factor.
In Mips when you use addi or any other commands in which you use a 16 bit value for a reg. value or address offset what operation is done to check if its is a negative number's two's complement or just a regular binary number
Determine a suitable sampling frequency. Design a notch filter to remove the 50Hz component, paying particular attention to any assumptions you have made in the design.
