Abstract
A mixed power supply device includes a power supply component for providing a DC voltage; a DC-DC conversion module coupled to the power supply component to receive the DC voltage and output a stable DC voltage; a current transformation module coupled between the DC-DC conversion module and a load to receive the stable DC voltage and convert the stable DC voltage into an AC voltage; and a merging network switching switch coupled to the current transformation module to connect the current transformation module and a utility power network in parallel or disconnect the current transformation module from the utility power network, allowing a load to receive merging network mode-based power supply or standalone mode-based power supply, wherein, in the merging network mode, the current transformation module performs unbalanced current compensation on load unbalance of the load.
