A new interleaved three-level inverter

The 2nd International Symposium on Power Electronics for Distributed Generation Systems, 2010
A new interleaved three-level inverter with reduced ripple current of filter inductor is proposed. This inverter consists of six power switches, including two interleaved power switches at the top location and the bottom location separately, and two double frequency power switches at the middle locations.

Synchronous Control of Cascaded Three-Level Inverters

2006 12th International Power Electronics and Motion Control Conference, 2006
Novel method of synchronous pulsewidth modulation (PWM) has been disseminated for control of cascaded neutral-point-clamped inverters feeding open-end winding induction motor drive with single dc voltage source. Control algorithms provide in this case full elimination of the common-mode voltages both in each inverter and in the load.

Intelligent cooling system for three level inverter

2015 Communication, Control and Intelligent Systems (CCIS), 2015
Three level inverter system produce voltage which consists of three different possible values. Inverter can be used to interface renewable energy sources with the grid. Temperature has significant effect on performance of power MOSFETs. Typically, MOSFET is used as power switch in such applications as it produce heat during operation, and the heat ...

Voltage spectra of three-level inverters

2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004
In the area of high voltages and powers, a high quality inverter-fed ac drive is more easily obtained by the use of multi-level inverters. For three-level inverters three different PWM control regions can be introduced where different two-phase (discontinuous) PWM strategies and the different three-phase ones should be applied.

Higher efficiency three-level inverter employing IEGTs

Nineteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2004. APEC '04., 2004
A higher efficiency is one of the important features required on large capacity converters. As high voltage and large capacity power semiconductor devices replacing conventional GTO thyristors, 4.5 kV IEGTs (injection enhanced gate transistors) and IGBTs have been placed on the market, for use in inverters for driving large motors of rolling mills ...

Implementing a three-level inverter with microcontroller

2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004
This paper shows the implementation steps of a three level inverter using microcontroller. The switching technique was the sine-triangle modulation. This technique is based on comparison of a desired sine voltage with two triangular carriers which frequency is very high. In this work some preliminary results are shown.

A novel forward-mode three-level inverter

2013 IEEE 8th Conference on Industrial Electronics and Applications (ICIEA), 2013
A circuit topology of the forward-mode three-level inverter is proposed. The kind of circuit topologies are constituted of three-level converter, high frequency transformer, output cycloconverter, output filter and so on. The inverter has the advantages such as simple topology, two-stage power conversions(DC/HFAC/LFAC), bidirectional power flow, high ...

Diode-Clamped Three-Level Dual Buck Inverter

2009 International Conference on Energy and Environment Technology, 2009
Dual Buck inverter(DBI) is a new topology which has the characteristics of high frequency and efficiency. But the output voltage of the bridge is a bipolar PWM waveform and voltage stress of the component in DBI is high, just like the half bridge inverter.

A three level natural clamped inverter (NCI)

IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003
This paper describes a zero voltage switched resonant inverter where focus is put on obtaining low power losses. Using zero voltage switching reduces the power losses of the inverter switching devices, however it is realized that the resonant circuit, introduced to obtain the zero voltage switching, is a major source of power loss that must be limited.
