Question:medium

The number of pulses per half cycle of PWM inverter is changed, then

Show Hint

The main goal of internal PWM control is to regulate the output voltage level without altering the fundamental operating frequency. - Internal pulse adjustments \(\rightarrow\) Changes total area \(\rightarrow\) Changes RMS Voltage. - Fundamental period stays fixed \(\rightarrow\) Frequency does not change.

\( \text{The rms output voltage does not change, but the frequency changes} \)
\( \text{Both rms output voltage and output frequency do not change} \)
\( \text{The rms output voltage changes, but the frequency does not change} \)
\( \text{Both rms output voltage and output frequency change} \)

Show Solution

The Correct Option is C
