Medha Servo Drives Technician Fitter Interview Questions and Answers

Q1. What are half wave and full wave rectifiers
Ans. 
Half wave and full wave rectifiers convert AC to DC, differing in efficiency and output waveform.
• Half Wave Rectifier: Uses one diode, allows only one half of AC waveform.

• Example: Simple power supply for low-power devices.

• Full Wave Rectifier: Uses two or four diodes, utilizes both halves of AC waveform.

• Example: More efficient power supply for higher power devices.

• Half wave produces pulsating DC, while full wave produces...read more

Q2. How can you filter a signal with ripples
Ans. 
Filtering signals with ripples involves using techniques to reduce unwanted oscillations while preserving desired signal characteristics.
• Use a low-pass filter to attenuate high-frequency ripples while allowing low-frequency signals to pass.

• Apply a moving average filter to smooth out rapid fluctuations in the signal.

• Consider using a Butterworth filter for a smooth frequency response with minimal ripples.

• Employ a Kalman ...read more

Ans. 
1 Tr of refrigeration is the amount of heat required to melt 1 ton of ice in 24 hours.
• 1 Tr of refrigeration is equal to 12,000 BTU/hr or 3.517 kilowatts.

• Newtonian fluids have constant viscosity, while non-Newtonian fluids have variable viscosity.

• Psychometric chart is a graphical representation of the thermodynamic properties of air-water mixtures.

• Entropy is a measure of the disorder or randomness in a system, while ent...read more
