Three-Phase Four-Leg Inverter Based on Voltage Hysteresis Control

2010 International Conference on Electrical and Control Engineering, 2010
As the output unit of variety distributed generation systems, the final power quality is determined by three-phase four-leg inverter. For the three-phase four-leg inverter, this paper presents a dynamic reference voltage hysteresis control scheme. Firstly, based on the existing hysteresis comparison method, this method improves the systems control ...

Design of the Neutral Line Inductor for Three-phase Four-leg Inverters

2019 IEEE Sustainable Power and Energy Conference (iSPEC), 2019
The three-phase four-leg inverter is one of the advanced solutions to feed unbalanced loads. However, the design of the neutral line hasn’t been well studied yet. This paper presents a mathematical model of the three-phase four-leg inverter with neutral line inductor, which is decoupled in the αβ0 coordinate and illustrates the effects of the neutral ...

Closed loop control of a four leg inverter for unbalanced power networks

2013 International Conference on Control Communication and Computing (ICCC), 2013
In this paper, a four leg inverter based compensator is proposed for unbalanced networks. The inverter is controlled in synchronously rotating reference frame consisting an outer voltage control and an inner current control. Zero sequence component of the system is also controlled in order to get a balanced output voltage when the system is distorted ...

A carrier-based discontinuous PWM modulation for four-leg inverters and applications

38th IAS Annual Meeting on Conference Record of the Industry Applications Conference, 2003., 2004
We review in this paper a carrier-based discontinuous pulse-width modulation (PWM) method for four-leg DC-AC inverters using an extended definition of the classical space vector methodology in which qd and the zero sequence components of the switching vectors enable the development of the expressions of the discontinuous modulation signals that clamp ...
