Question 1
A UPS is driving a 600 W and which has a lagging power factor of 0.8. The efficiency of the inverter is 80%. The batter voltage is 24 V DC. Assume that three is a separate charger for the battery. What is the rating of the inverter?
Question 2
For a single-phase full bridge inverter, inductive reactance is double that of capacitive reactance. Also, resistance is same as that of capacitive reactance. Then, Diode conduction angle is____
Question 3
A single phase full bridge inverter controls the power in a resistive load by uniform multiple pulse modulation. The frequency of triangular carrier wave is 1kHz and inverter reference wave frequency is 125Hz. If the total pulse width is 120°, find the width of each pulse?
