Low THD voltage source involving two sliding mode controllers
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012This paper deals with a converter using two legs of inverters which operate in parallel and act as current and voltage sources. This is done in order to increase the output power and to get a low output voltage harmonic distortion. One of the legs implements IGBTs and acts as the slave current source, when the other leg implements MOSFETs and acts as ...

A Single-phase Asymmetrical Multi-Level Inverter with a Low THD
2018 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2018The utilization of multilevel inverter have been increased since the last decade. These type of inverters get better voltage waveform, and decrease total harmonic distortion (THD). This paper presents the design and simulation of a single-phase asymmetrical multilevel inverter.

Control of three phase power supplies for ultra low THD
[Proceedings] APEC '91: Sixth Annual Applied Power Electronics Conference and Exhibition, 2002Current regulators are proposed and investigated for high-power three-phase power supplies with ultra-low total harmonic distortion (THD) (less than 0.5%). Two valid approaches to realize three-phase power supplies can be proposed. In the first approach, current regulated pulse-width-modulated (PWM) inverters along with high bandwidth voltage control ...

Isolated low-output-voltage PFC circuit with integrated magnetics: Design for low THD
2010 IEEE International Symposium on Industrial Electronics, 2010This paper presents a detailed analysis of a Single-Stage Single-Switch Power Factor Corrector, S4PFC, with Integrated Magnetic, IM. The chosen topology for study for implementing S4PFC is based upon a Boost Converter operating in Discontinuous-Mode for Input Current Shaping, and a Forward Converter for output voltage regulation. Detailed are the modes

A new single switch bridgeless SEPIC PFC converter with low cost, low THD and high PF
2015 9th International Conference on Electrical and Electronics Engineering (ELECO), 2015In this paper, a new single switch bridgeless AC/DC power factor correction PFC converter topology to achieve high PF and low THD is proposed. The proposed converter is based on the single ended primary inductance converter SEPIC topology. The SEPIC converters can operating from an input voltage that is greater or less than the output voltage.

Zero-crossing distortion analysis in one cycle controlled boost PFC for Low THD
2011 9th IEEE International Conference on ASIC, 2011A low-power low THD boost PFC with one cycle control is discussed. Two novel structures, the periodic self-starting timer and feedforward current control block, are introduced to reduce the zero-crossing distortion. The improved boost PFC could regulate the switch turn-on time timely according to the ac input line voltage, and reduce the distortion ...
