A novel three-level PV inverter

2012 7th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2012
A novel three-level buck-boost type inverter is proposed in this paper. It combines the series-parallel diode-capacitor network with the traditional buck-boost converter, plus the full bridge inverter as the back stage. The new inverter can boost or lower the input voltage.

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.

Soft switching three level inverter (S3L inverter)

2013 15th European Conference on Power Electronics and Applications (EPE), 2013
The Soft Switching Three Level Inverter - abbreviated to S3L Inverter - was first introduced in 2011. It is a novel circuit topology for PWM inverters, whose areas of application include electrical drives and grid-tie inverters for photovoltaic installations and wind power plants, and for power supplies.

PWM Three-Level Inverter Control

2006 IEEE International Conference on Automation, Quality and Testing, Robotics, 2006
This paper analyses a PWM control circuit for a three-level three-phase inverter. The power circuit of inverter and the PWM control principles, using a mirror triangular waveform, are explained. The output voltages of the inverter are represented by 21 Park vectors, from which 3 vectors are null.

Three level rectifier versus three level inverter with DTC controlled induction motor

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
A three level NPC-rectifier versus three level NPC-inverter with direct torque controlled asynchronous motor is examined. Three level inverters have the problem of the DC-link voltage balance, especially if DTC control is considered. To reduce the problem both DC voltage and the potential of its middle point are controlled through a three level V.S.R ...

Optimal pulse width modulation for three-level inverters

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004
The three-level neutral-point-clamped voltage source inverter is widely used in high power, medium voltage applications. This paper studies continuous and discontinuous PWM for this inverter. Detailed analysis of discontinuous modulation shows that the average switching frequency is not directly proportional to the carrier or sampling frequency, since ...

Detection and compensation of switch faults in a three level inverter

2006 37th IEEE Power Electronics Specialists Conference, 2006
This paper deals with open and short-circuit switch faults in a three-level inverter feeding a three-phase induction motor. It also investigates the fault compensation via topologies that are able to maintain the system operation for a period of time. Simulated and experimental results verify the feasibility of proposed strategies.

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.

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.

A new current control for three-level inverter

Proceedings of IEEE. IEEE Region 10 Conference. TENCON 99. 'Multimedia Technology for Asia-Pacific Information Infrastructure' (Cat. No.99CH37030), 2003
A new current controlled PWM technique for a 3-level inverter has been proposed and described in the paper. The proposed current control has the simple structure without needing to-calculate the switching angles of the voltage vectors. The output in the proposed inverter contains less harmonic content than that of a conventional current controlled PWM ...
