Pulse width modulation for current source inverters with arbitrary number of phases [PDF]
Scientific ReportsModulation techniques for current source inverters (CSIs) have traditionally been derived from those used for voltage source inverters (VSIs), with space vector modulation (SVM) and pulse width modulation (PWM) being the most popular. Among these, PWM is

Low‐power pulse width modulation (PWM) for high‐frequency DC–DC converters [PDF]
Electronics Letters, 2018 A low‐power pulse width modulation (PWM) control circuit for high‐frequency switching direct current (DC)–DC converters based on a one‐shot circuit is proposed. The proposed PWM control circuit eliminates the use of a high‐power comparator and ramp generator that is conventionally used to generate the PWM waveform.
