design a rectifier filter circuit, which will have:
Vs=310 V (Vrms=219 V) at the input of bridge rectifier
Need LC filter at the output of bridge which can provide 240 V +-10V DC, with 2 A constant current. find method to find appropriate values of LC which can provide these specification.
Hint: Make inductor to work in discontinuous mode so that output voltage could be adjusted along with current.
A transformer is used to match an 8 ohm speaker to a 500ohm audio line. What is the turns ratio of the transformer what is the input voltage and output voltage when 15W is being delivered to the speaker
If L=0.0053nH, C=15µF find the operating frequency of series LC circuit. What factors decides capacitance? Explain using diagram.
Power Electronics - Diode, [Power electronics] The measured values of a diode at a temperature of 25 Degrees Celsius are: Vd=1V at Id=50A, Vd=1.5V at Id=600A. Determine (i) the emission coefficient n, and (ii) the leakage current.
Design a counter to count even numbers between 0 and 15. Therefore states will be 0 -> 2 -> 4 -> 6 -> 8 -> 10 -> 12 -> 14 -> 0. If any unused state is encountered bewteen 0 and 7, then the counter should go back to initial state 0.
