“…The role of this rectifier module is to control the input power factor, rectify the input AC voltage to DC-links, and balance the voltage of DC-links. In this paper, the phase shift pulse width modulation (PSPWM) scheme was adopted for CHB rectifier modules because it is easy to use and reliable [33,34]. The single phase d-q coordinate controller was also adopted for voltage balancing of the DC-link as presented in [35].…”

One of the main disadvantages of the multi-level solid-state transformer (SST) system is the voltage imbalance on the output of the rectifier modules. This voltage imbalance can be caused by parameter mismatch of the active and passive components, different loads, and the floating structure of the high voltage DC-links. Some studies have been done to solve this voltage imbalance problem. A common way to avoid this imbalance is to balance the voltage of DC-links at the AC/DC conversion stage and balance the power between the modules at the DC/DC conversion stage. Most of these methods require a complex balancing controller or additional circuits. This paper proposes a novel dual active bridge (DAB) converter specialized in power balancing in a single-phase 5-level SST system. The proposed DAB converter does not require any additional balancing controllers or techniques for power balancing. The performance of the proposed DAB converter was verified by simulation and experiments using a 3 kW 5-level SST prototype system.

“…They have tried to develop algorithms to extract the maximum energy converted by the panel and then that allows optimal operation of the photovoltaic system [1].The PV module is essentially standard PV panel and DC-DC converter with MPPT Controller the modular power electronics technology named multilevel inverter.There are three topologies commonly used at multiple levels of theinverter such as diode inverter, capacitor inverter flyer and multilevel inverter cascade. Among the above cascaded topologies, H-bridge topology is the most suitable for the integration of renewable energy.It is usedseparately Source DC can be powered from the PV panel [5] [6]. H-bridge in cascade the multilevel inverter is better than the other two types of multilevel inverter because of this require less component, the cascade topology allows the use of DC source with different voltage values, same input voltage the output voltage obtained with H-bridge in cascade the multilevel inverter is twice as much as the output voltage with diode capacitor and flywheel capacitor and bridge power H cell connected in series to produce a high AC voltage.…”

This article presents the five levels H-Bridge cascaded multilevel inverter with photovoltaic MPPT control. The power source is composed of photovoltaic panels used as DC inputs for the cascaded H-Bridge Multilevel Inverter. The present work aims to present a control strategy to produce the best output quality possible. The algorithm P&O extract from the panels the maximum power while the supervision system tends to control the DC levels in the CHMLI inputs. Each panel possesses its own MPPT module and the cascaded H-Bridge Multi-Level Inverter uses the modules as entries to produce a staircase waveform output. A simulation using matlab/simulink is realized to verify the system performance.

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.
