A diode-clamped multilevel inverter with voltage boost function

8th International Conference on Power Electronics - ECCE Asia, 2011
Multilevel inverters are mainly used in high power and medium voltage applications to reduce the required voltage rating of the power semiconductor switching devices. On the other hands, these multilevel inverters are attractive for various applications regardless of the power ratings because they can essentially realize lower harmonics with lower ...

A New Reduced Switch Diode Clamped Multilevel Inverter Topology

2020 IEEE International Conference on Computing, Power and Communication Technologies (GUCON), 2020
In this work, a new diode clamped multilevel inverter topology with reduced switches and component counts is proposed. This topology can generate desired level of output voltages with lower number of switches and clamping diodes. A scaled version of the proposed topology is discussed with relevant figures of merits. Two different levels of inverters (5

Hybrid SVPWM strategy for diode-clamped 3H-bridge inverter

2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014
The paper presents a novel space vector modulation strategy for a single phase three-level neutral-point-clamped(NPC) inverter. Based on the operating principle of NPC inverter, this strategy overcomes one of the main problems of this inverter, which is the DC-link capacitors voltage unbalancing problem that appears in the neutral point under some ...

Experimental verification of loss reduction in diode-clamped multilevel inverters

2011 IEEE Energy Conversion Congress and Exposition, 2011
Recently, power converters with lower power loss and lower electromagnetic interference (EMI) are required in many applications. To satisfy these requirements, diode-clamped multilevel inverters are investigated. In this case, the voltage balancing circuit must be connected to the DC capacitors because the DC voltages tend to unbalance when the number ...

Diode Clamped Three Level Inverter Using Sinusoidal PWM

2012 International Conference on Communication Systems and Network Technologies, 2012
An inverter is a circuit which converts dc power into ac power at desired output voltage and frequency. The a.c. output voltage can be fixed at a fixed or variable frequency. This conversion can be achieved by controlled turn ON & turn OFF or by forced commutated thyristors depending on applications.
