Improved natural balancing with modified phase shifted PWM for single-leg five-level flying-capacitor converters [PDF]
, 2012 Flying capacitor converters (FCCs), as most multilevel converter topologies, require a balancing mechanism of the capacitor voltages. FCCs have the valuable property of natural voltage balancing when a special modulation technique is used.

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.

FPGA Implementation of a General Space Vector Approach on a 6-Leg Voltage Source Inverter [PDF]
, 2011 A general algorithm of a Space Vector approach is implemented on a 6-leg VSI controlling a PM synchronous machine with three independent phases. In this last case, the necessity of controlling the zero-sequence current motivates the choice of a special ...

A nearest level PWM method for the MMC in DC distribution grids [PDF]
, 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 number. This paper
