This paper designs DC motor and stepping motor controllers based on MSP432P401R micro-controller unit (MCU). MSP432P401R alleviated MCU generates pulse width modulation (PWM) signal, which controls ...

Due to the lack of sufficient redundant states, four-level nested neutral-point clamped (4L-NNPC) converters suffer from severe flying capacitor (FC) voltage fluctuations under low fundamental ...
