DC-link Voltage Balancing Strategy based on SVM and Reactive Power Exchange for a 5L-MPC Back-to-Back Converter for Medium Voltage Drives
(IEEE, 2016)
The reduced capability of multilevel converters with more than one intermediate node to balance the dc-link capacitors voltage, as well as the lack of standard modulation methods to improve their balancing performance, ...
Simple voltage balancing method to protect series-connected devices experimentally verified in a 5L-MPC converter
(IEEE, 2018)
This paper presents a solution for the voltage balance problem of the series-connected devices that can be applied to multilevel converters in which the series-connected devices need to block twice their switched voltage. ...
DC-Link Neutral Point Control for 3L-NPC Converters Utilizing Selective Harmonic Elimination PWM
(IEEE, 2021)
Selective harmonic elimination–pulsewidth modulation (SHE–PWM) is a modulation technique widely used to improve the efficiency and harmonic content in medium-voltage high-power converters. Among these converters, the ...
Comprehensive analysis of voltage balancing techniques for 5L NPC converters
(IEEE, 2013)
The reduced capability of the 5L-NPC Inverter to balance the voltages of the four DC-bus capacitors makes this converter unattractive for real power applications. This is especially true if the load demands active power. ...
Benefits of switching from Si to SiC modules with further converter optimization
(IEEE, 2022)
SiC semiconductors have better characteristics than Si, improving power electronics converters performances. A prototype that can switch semiconductor technology without changing any other part of the system is built and ...
