Grid Integration of a Single-Source Switched-Capacitor Multilevel Inverter with Boosting Capability
This paper investigates the connection of a single-phase multilevel inverter structure to an existing power grid. The applied voltage source inverter is able to generate a near sinusoidal voltage waveform with an amplitude six times the input voltage by using a single DC input power supply. A proportional-resonant (PR) controller regulates the injected current into the grid. While the EPLL is u...
متن کاملNew Cascaded Multilevel Inverter With Reduced Power Electronic Components
In this paper, a new structure for cascade multilevel inverter is presented which consists of a series connection of several sub-multilevel units. Each sub-multilevel unit comprises of eight unidirectional switches, two bidirectional switches, and six DC voltage sources. For the proposed cascade topology, two algorithms are presented to produce all possible levels at the output voltage waveform...
متن کاملHigh-Frequency AC Power Distribution System with a Cascaded Multilevel Inverter Based on Switched-Capacitor
The increase of transmission frequency reveals more merits than lowor medium-frequency distribution among different kinds of power applications. Highfrequency inverter serves as source side in highfrequency ac (HFAC) power distribution system (PDS). However, it is complicated to obtain a highfrequency inverter with both simple circuit topology and straightforward modulation strategy. A novel sw...
متن کاملA Step-Up/Step-Down Switched-Capacitor AC-AC Converter with Symmetrical Topology
In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. ...
متن کاملA New Single-phase Symmetrical Cascade Multilevel Inverter with Low Number of Power Switches
In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...
