OFF-LINE PHASE SPLIT DEVICE AND INVERTER SYSTEM

This application provides an off-grid phase splitter and an inverter system. In an embodiment, the off-grid phase splitter includes: a first input port and a second input port that are separately connected to a first phase port and a second phase port of a power supply; a first output port and a second output port provide a second voltage for a first load, and the second output port and a third output port provide a third voltage for a second load; a first capacitor and a second capacitor, where the first capacitor is connected between the first output port and the second output port, and the second capacitor is connected between the second output port and the third output port; a first switch circuit and a second switch circuit, where the first switch circuit and the second switch circuit are connected in series between the first input port and the second input port, the first switch circuit and the second switch circuit are unidirectionally switched on in opposite directions, and a first node is disposed between the first switch circuit and the second switch circuit; and an inductor, where the inductor is connected between the first node and the second output port.
