At first I was asked about my project on power electronics from my resume and I was asked to explain the working of my projects and also draw the block diagram and explain regarding the same. Next I was asked questions related to 1st order RC circuits and, I was given a basic circuit of R and C and then asked to draw the output waveform of Voltage across Capacitor. Then the complexity of the circuit was increased by adding Resistors and capacitors across the initial circuit and was asked to draw the output waveform of voltage when step input was given. Then an RC circuit was given and Time constant of the circuit was mentioned and also a pulse input was given and was asked to draw the circuit. Finally some basic questions on Opamp feed forward and feed backward circuit analysis was asked.
