Two-level operation of a diode-clamped multilevel inverter

2010 IEEE International Symposium on Industrial Electronics, 2010
This paper presents space vector based quasi two-level operation of a diode-clamped multilevel inverter in an attempt to improve the dc link utilization and output voltage quality, and avoids dc link capacitor voltage balancing problems experienced with standard multilevel operation.

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 ...

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 ...

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

Phase-Controlled Class-D ZVS Inverter with Clamp Diodes

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
This paper proposes the phase-controlled class-D inverter with clamp diodes. In the proposed inverter, one of the resonant inductance is divided into two components and clamp diodes are added to the middle point of the divided inductance. By adding the clamp diodes, over currents can be suppressed effectively.
