Comparison of Harmonics Between SVPWM and SHEPWM

2018
The traction system of rail transit has the characteristics of low switching frequency and wide speed range, and generally adopts “asynchronous modulation + synchronous modulation + square wave” full-speed range pulse width modulation strategy. In order to realize the smooth transition from asynchronous modulation to square wave modulation, many ...

m-Mode SVPWM for Multilevel Inverter

2019
Compared with the aforementioned two-level inverter, the multilevel inverter can further reduce the harmonics of the output voltage and current. However, the structure of the multilevel inverter is more complicated, which makes the design of the SVPWM switching sequences more difficult.

Study on hybrid SVPWM sequences for two level VSIs

2017 IEEE International Conference on Industrial Technology (ICIT), 2017
Space vector pulse width modulation (SVPWM) is widely used because of their easier digital realization and better DC bus utilization and lower THD. Various types of SVPWM strategies exist. The hybrid SVPWM strategy considers various SVPWM sequences and places the best performance sequence for a given reference vector and it proves to be superior in ...

A new fault tolerant SVPWM strategy for multilevel converters

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
Fault tolerant and survivable operation schemes for multi-level converters, that interface the grid and critical loads, have been gathering attention for enhanced reliability. In case short-circuit or open-circuit faults occur in one or multiple voltage cells, the space vector pulse width modulation (SVPWM) control algorithm has to be modified ...
