2. Find the total harmonic distortion from a VSI as a function of the relative phase angle 8.

14. Derive the expressions of average and rms values of output voltage of step-down/step-up chopper.

Explain the following tradeoffs: Error performance vs bandwidth

A step-up chopper has input voltage of 220v and o/pvoltage of 660v. If the non-conducting time of the thyristorchopper is 100μs compute the pulse width of the outputvoltage . If the pulse width is halved for constant frequencyoperation Find the new output voltage and chopper frequency

I need proper solution for the following( underdstandable writing and well explained) thank you  What is resonance in LCR circuit? and tell the difference between impedance and resistance?

Consider a step down converter with a resistive load. It is supplied by a DC power source of magnitude Vs 160 V. The switching period is 0.25 ms and the duty cyclek is first set to 0S. The load is resistive with R-10 OHMS. When the switch is ON, a voltage drop across the switch is noted of Vch 1V. The RMS output voltage vo is equal to 1124V. The RMS input current and the conduction losses are equal to: Select one: O a.7.95A and 7.95W O b. 11.24A and 11.24w OC. None of these O d. 11.24A and 1263W

The term duty cycle refers to the amount of time a signal is complete cycle. A. off compared to the period of one B. on The output voltage of op-amp is positive saturation, when the voltage applied to the input is greater than the input. A. inverting B. noninverting A square wave that is 20V at its high state and OV when it is off will produce an average DC when its duty cycle is 75%. Formula: VOUT = Duty Cycle * Peak voltage voltage of A. 7.5V B. 10V C. 15V

Q1. For the MOSFET circuit below, input is sinusoidal signal of amplitude IV and frequency 50Hz. Find, the DC operating point, Plot the frequency response and Plot the input, output and transfer characteristics and find out the small signal equivalent. Assume an overdrive voltage of 0.2V Use MOSFET 500nm Library file provided. F Vdd=5V -=80 K R1 (1 1.20F

A force transducer system is needed to measure a sinusoidal signal. Derived from the logarithmic amplitude decay test, the system has a damping ratio of 0.6 and natural frequency of 1500 Hz. Estimate the frequency bandwidth of this system and plot M(f). What is the upper cut-off frequency?

d) Parasitic capacitances usually exist in a practical amplifier. Comment on the possible sources of the parasitic capacitances. How they are likely to affect the frequency response of the amplifier.
