Topologies and control of grid connected power converters
2014 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2014], 2014This paper presents an overview of current control practices for three phase power converter acting as an asynchronous interface between a synchronous voltage source and a power electronic controlled voltage source. The paper starts with glimpse of the common topologies, and branches out to the control techniques from linear to non-linear, dc loops to ...

A 1kW Grid-Connected Converter System for PEFC
2007 Power Conversion Conference - Nagoya, 2007We have developed a small-size high-efficiency grid-connected converter system for a 1 kW PEFC (polymer electrolyte fuel cell) unit, which consists of a novel isolated DC-DC converter and a single-phase inverter whose output voltage is 200 V. In order to reduce reverse recovery losses of diodes in the secondary circuit of the DC-DC converter, two ...

An improved active damping control in grid-connected converter system
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Grid-connected converters have been widely used in distributed generations. However, the resonance brought by converters in weak grid has been a great threat to system stability. Impedance-based method provides a powerful tool for stability analysis. Active damping is also widely applied to improve system stability.

Direct Power Control of Grid Connected Voltage Source Converters
2007 IEEE Power Engineering Society General Meeting, 2007This paper proposes a new direct power control (DPC) strategy for grid connected voltage source converters (VSC). Similar to an electrical machine, source and converter flux are defined as the integration of the source and converter voltage respectively.

Circulating Current Suppression of Parallel Photovoltaic Grid-Connected Converters
IEEE Transactions on Circuits and Systems II: Express Briefs, 2018The photovoltaic (PV) grid-connected converter (GCC) is a critical interface between solar energy and the power grid. Improved efficiency is possible if several PV GCCs have a common array bus. However, the dc side shunt causes the circulation of a zero-sequence current, which will distort the GCC or even damage semiconductor devices. The zero-sequence
