Q1. A single phase voltage source inverter is controlled in a single pulse width modulated mode with a pulse width of 150^o in each half circle. Total harmonic distortion is defined as

THD = (√(Vrms²- V₁²))/V₁ * 100

Where V₁ is the rms value of the fundamental component of the output voltage. The THD of output 'ac' voltage wave form is..

Q2. Find the voltage gain of the following op-amp network.

Q3. CE amplifier Problem - An amplifier ckt shown in fig where V_t = 25mV and β is very large

Voltage gain = V_o/V_s

Key Points -

1. r_e = V_t/((It)φ)

2. A_v = (-Rl)/re (open loop)

3. A_v = (-Rl)/RE (close loop)

4. A_vs = A_v (R_i)/(R_i+R_c)

Q5. Find the maximum power dissipation in the load.

Q6. In a single-phase full wave diode bridge rectifier, the diodes have a reverse recovery time if 40 μs. For an 'AC' input voltage of 230v, determine the effect of reverse recovery time on the average output foe a supply frequency of 50 Hz.
