Question 3: DC-AC Converters (Inverters)
a. Draw the circuit diagram of a single-phase full bridge dc-ac inverter using 6 switches and 6 diodes supplying a resistive load.
b. Draw the waveforms of the output voltage $v_o$ and fundamental current load current $i_{o1}$ of the dc-ac converter with a resistive load.
c. A single-phase full bridge inverter has a purely resistive load $R = 5 \Omega$ and the dc input is $V_s = 220 V$. Determine: (i) the rms output voltage at the fundamental frequency $V_{o1}$, and (ii) the output power $P_o$.
