How can we define "Modulation" specifically wrf to Power Converters?

15 April 2017 1 5K Report

I know what PWM is, but I couldn`t quite make sense of the term modulation when I come across statemets like:

"an effective approach is just employing single-edge modulation as pulse-width modulation (PWM) in both PFC and DC/DC converter"

What do we mean by modulation, specifically when talking about Power Electronics Converter?

Vishwanath Gupta

Modulation means to control the width of the gate pulse as required in the application
