2. A single-phase haif--bridge inverter is connected to a 600 v d.c. source. A series ted R-L load has R= D0 onm, L 70mH. The inverter frequency is 60 Hz. Determine the values of therms load current, the load power and the total harmonic distortion factor, up to the 11th harmonic.

A three phase inverter below has a Y- connected load. The inverter frequency is fo = 60 Hz and the DC input voltage Vs = 220V. The applied control signal is a 180 deg conduction mode. The RMS Line to Line voltage Vo is equal to 179.63V. The total harmonic distortion (THD) is equal to: Select one: a. 48.34% b. 31.08% c. None of these d. 100%

for square wave PWM inverter, Vdc=100V, L=25mH, R=1002, f=60Hz. draw the spectrum of the output voltage and current and then find the rms current value and the output power. Take n =1-20.

Using the sine PWM method with the full bridge inverter below, it is desired to generate a voltage of 50Hz on the series RL load. A voltage of 120 V DC is applied to the input of the inverter circuit. Amplitude modulation rate ma = 0.9 and frequency modulation rate mj = 19. The resistance of the series RL load is 15 ohms and the coil inductance is 40 mH. What is the total harmonic distortion value (THD) of the power drawn by the load resistor and the load current?
