The current switching ripple in a three-phase four-wire split-capacitor converter is analyzed this paper for all the four ac output wires relation to both balanced and unbalanced working conditions. Specifically, analytical formulations of peak-to-peak root mean square (RMS) ripples are originally evaluated as function modulation index, separately three phases neutral wire. Initially, single-ca...

The fundamental principle of SVPWM is introduced in this study. The design on the structure of threephase voltage type PWM rectifier system based on SVPWM control was also discussed. Then we calculate the DC capacitor and AC side inductance. The computer simulation tool MATLAB/Simulink is taken and the result is shown in the end. The result indicates that the design of such platform is feasible.

Three-phase back-to-back converters are widely applied in various industrial, commercial, and domestic applications, such as AC motor drives. Due to the non-sinusoidal voltages they generate, a common mode voltage (CMV) appears, leading problems electrical drive systems high-frequency applications. The CMV rapid changes can cause serious problems, including leakage currents flowing through para...

Medium voltage hybrid bridge multilevel converter (MMC) usually has a lower number of links. Therefore, the traditional Nearest Level Modulation (NLM) method problems low equivalent switching frequency and poor output quality. And Carrier Phase-shifted Pulse Width (CPS-PWM) modulation such as difficulty in control, redundant configuration, large amount calculation. In response to above problems...
