Manufacturers of PV inverters and energy storage systems are increasingly turning to silicon carbide power modules to increase the efficiency of their solutions. This article discusses how to implement hybrid active neutral point clamped (ANPC) inverter topology with synchronous rectification to balance efficiency and cost for common applications.
Researchers in photovoltaic power generation are very interested in the multilevel inverter topology due to its exceptional qualities. In recent years, numerous multi-layer topologies, such as neutral point clamp, flying capacitor, and Cascaded H Bridge (CHB), have been created to address the demand for high power scale , , , .
The buck nature of the VSI output voltage necessitates the use of a boost converter between the energy storage and the inverter, which adds more switches, controls, and complexity. By using a multilevel inverter in place of VSI partly or entirely, the need for filters can be eliminated, resulting in fewer switching losses.
In the single-phase photovoltaic energy storage inverter, H4 bridge topology is widely used in the bidirectional AC/DC circuit at the grid side because of its simple structure and low cost, so as to realize the bidirectional energy flow between the grid and the energy storage battery [ 4, 5 ].
The voltage restoration is achieved by the capacitors as energy storage using the zero active power compensation technique. DVR with a cascaded H-bridge multilevel converter [ 144 ]. DVR with five levels reduced the number of power circuit components.
TCHB inverter [ 259] was used to mitigate the voltage sag using two voltage compensation schemes, in-phase and presag compensation. In [ 260 ], the authors proposed an S4L inverter-based DVR with a single DC power source and reduced switch count; thus, it is more cost-effective.
