Questions & Answers

Q: What is single pulse width modulation?

Single pulse width modulation is a method of controlling the output voltage of an inverter by adjusting the width of a pulse. By changing the width, the output voltage can be controlled effectively.

Q: How does multiple pulse-width modulation work?

Multiple pulse-width modulation involves using multiple pulses and changing the width of these pulses to control the output voltage of an inverter. By adjusting the width of each pulse, the overall output voltage can be regulated.
