Digital PWM waveform generation using adders, not counters [PDF]
, 2004 An alternative approach to digital PWM generation using an adder rather than a counter is presented. This offers several advantages. The resolution and gain of the pulse width modulator remain constant regardless of the module clock frequency and PWM ...

Advanced resampling techniques for PWM amplifiers in real-time applications
, 2017 Regularly sampled pulse width modulation (PWM) has been a mainstay of the power electronics community since the advent of digital controllers. In this form of PWM the modulating signal is sampled only at either the peaks and/or the troughs of the ...

A novel current-tracking method for active filters based on a sinusoidal internal model [for PWM invertors]A new current control method based on the internal model principle in control theory is proposed. It introduces a sinusoidal internal model into the control system. It does not use any coordinate transformations. The method can be used for tracking an arbitrary number of harmonics: a DC component or fundamental frequency component signal. It is applied

Reduction of Torque Ripple in Induction Motor Drives Using an AdvancedHybrid PWM Technique
, 2010 A voltage source inverter-fed induction motor produces a pulsating torque due to application of nonsinusoidal voltages. Torque pulsation is strongly influenced by the pulsewidth modulation (PWM) method employed.
