Two phase inverter series power supply is widely used in high-end portable power supply or household energy storage system

Two phase inverter series power supply is widely used in high-end portable power supply or household energy storage system because of its bidirectional charging and discharging function. The bidirectional inverter has a complete control strategy, which can comprehensively manage the energy of the mains/battery/load, and perform AC-DC white dynamic conversion. In the absence of a grid, it can directly supply power to the AC load. In the case of a grid, the grid directly supplies the AC load, and at the same time charges the battery with a large rate (up to 1C) to charge and store energy. It is a truly integrated charging and discharging machine.

Two phase inverter series power supply mainly includes the following units: battery buck-boost unit (isolated bidirectional DC/DC), DC/AC inverter unit, mains inverter switching unit, and two DC/DC outputs. In addition, there are main control unit, battery auxiliary power supply, mains auxiliary power supply, drive module MPPT module, etc.
