Question 1
The circuit shown is meant to supply a resistive load RL from two separate DC voltage sources. The switches S1 and S2 are controlled so that only one of them is ON at any instant. S1 is turned on for 0.2 ms and S2 is turned on for 0.3 ms in a 0.5 ms switching cycle time period. Assuming continuous conduction of the inductor current and negligible ripple on the capacitor voltage, the output voltage V0 (in Volt) across RL is ______________.
Question 2
In single pulse modulation of PWM inverters, third harmonic can be eliminated if pulse width is equal to
Question 3
Calculate the R.M.S value of the fundamental component of current, in a single phase half bridge having a resistive load of 10Ω and Supplied by an input dc voltage of 50V?
Question 4
In the Buck circuit shown, when the Diode is reverse biased by voltage source then:
Question 5
“Six MOSFETs” connected in a bridge configuration (having no other power device) MUST be operated as a Voltage Source Inverter (VSI)”. This statement is
Question 6
In the following chopper, the duty ratio of switch S is 0.4. If the inductor and capacitor are sufficiently large to ensure continuous inductor current and ripple free capacitor voltage, the charging current (in Ampere) of the 5 V battery, under steady-state, is _______.
