A flyback converter is to be designed so that it operates in continuous "current" (flux) mode with a duty cycle of D = 0.45 when input voltage Vs = 48 V, output voltage Vo = 30 V, switching frequency fs = 25 kHz, and load resistor R = 15 W. Determine the necessary transformer turns ratio and transformer magnetizing inductance that will make the minimum inductor current to be 25% of the average. Confirm your answer with PSIM.
Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
Q. Three single-phase, 10-kVA, 2400/120-V, 60- Hz transformers are connected to form a three- phase, 4160/208-V transformer bank. Each of the single-phase transformers has an equiv
What Is the Concept of Dual beam CRO ?
why we rotate the armature of dc motor in anticlockwise direction
Q. What do you mean by Counters? The shift register can be used as a counter because the data are shifted for each clock pulse. A counter is a register that goes through a pred
The various flags are: - Sign flag, Axillary flag, Zero flag, Parity flag, Carry flag.
Execution Unit receives program instruction codes and data from BIU, implements these instructions and store the result in general registers.
Consider the magnetic circuit of Figure with an air gap, while neglecting leakage flux. Correct for fringing by adding the length of the air gap l g = 0.1 mm to each of the other
