Analysis of VCO based noise shaping ADCs linearized by PWM modulation [PDF]
, 2012 Nonlinearity is one of the main problems associated with VCO based noise shaping ADCs. Their open loop architecture does not permit correction of the nonlinear voltage to frequency response of the VCO by feedback.

A Nearest Level PWM Method for the MMC in DC Distribution Grids
IEEE transactions on power electronics, 2018 For modular multilevel converters (MMCs) applied to medium-voltage dc distribution grids, using the traditional nearest level modulation (NLM) as in HVdc systems can lead to severe current distortion due to significantly reduced module numbers.

Two-step commutation control of switched reluctance motor based on PWM
The Journal of Engineering, 2019 Aiming at the noise suppression of switched reluctance machine (SRM), the two-step commutation control method is improved. Combining this with pulse width modulation (PWM), the optimisation problem of the switching angle is studied and analysed and given

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
, 2018 In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...
