Abstract
Disclosed herein are bi-directional DC converter circuits and control methods. In one embodiment, a method of controlling a bi-directional DC converter, can include: (i) detecting whether there is an input power supply at an input port, where the bi-directional DC converter comprises a single magnetic element; (ii) operating the bi-directional DC converter in a first operation mode to charge a battery when the input power supply is detected at the input port; (iii) operating the bi-directional DC converter in a second operation mode to transfer power from the battery to an output port for a load when the input power supply is not detected at the input port; and (iv) transferring power through the single magnetic element in both the first operation mode and the second operation mode.
