Comprehensive study on space-vector-PWM and carrier-based-PWM correlation in multilevel invertors
IEE Proceedings - Electric Power Applications, 2006 The paper presents a theoretical analysis of the correlation between carrier-based unipolar PWM (CPWM) and space-vector PWM (SVPWM) for the entire modulation-index range of multilevel invertors, including overmodulation. By presenting corresponding parameters of vector redundancies in a zero-sequence function, the carrier-based PWM has matched the ...

Improving voltage imbalance in inverter‐based islanded microgrids during line‐to‐line short circuits
IET Power Electronics, 2023 Line‐to‐line short circuits are the transient disturbances that cause the highest currents as well as the largest voltage imbalances in inverter‐based microgrids. This paper presents a control scheme for grid‐forming inverters in islanded microgrids that

Comparison of single- and double-sided pulse width modulated signals with non-linear predistortion [PDF]
, 2012 Class D amplifiers are based on a low-bit pulse width modulated (PWM) signal reconstructed through the lowpass characteristic of the loudspeaker. To create a PWM signal, a non-linear conversion from a standard pulse code modulated (PCM) signal has to be ...
