Is a DC-AC bidirectional energy storage converter based on phase-locked loop tracking control?

5. Conclusion In this paper, a DC-AC bidirectional energy storage converter circuit based on phase-locked loop tracking control combined with HERIC circuit is proposed.

What is a bidirectional DC-DC converter?

The energy transfer in PV systems heavily relies on efficient bidirectional DC-DC converters. To ensure stable operation, converters with high reliability and power density are required. This paper introduces the basic principles and topologies of bidirectional DC-DC converters and provides a comparative analysis.

How does a DC energy storage system work?

The system not only converts DC storage energy to the loads or the grids bidirectionally, but also supplies high quality power, such as low total harmonic distortion (THD) current to the girds or the load consumers, or low ripple charging current to the energy storage units.

What is a bidirecion DC-AC inverter?

The bidirecion DC-AC inverter transfers power from the DC stage to the connected AC grid while the DC loading requirement is small. Or, the inverter transfers the power from the connected AC grid to the DC stage if the DC energy is insufficient for the DC loading requirement. In this document, basic knowledge of the inverter is presented first.

Can a phase-locked loop based DC-AC converter be used in power supply systems?

This shows that exploring the application of clean energy in power supply systems is increasingly becoming a hot topic in society . In this regard, the paper proposes the use of a phase-locked loop based DC-AC converter as an energy conversion device to be integrated into the power grid.

Can a medium converter reduce rated power of a photovoltaic system?

A dual-mode control strategy is proposed, which realizes ZVS and low switching noise. In reference , the medium converter can reduce the rated power of the photovoltaic system and improve the efficiency of the photovoltaic system.
