摘要： A bidirectional DC/DC converter and an energy storage system are provided. The bidirectional DC/DC converter includes: a first half-bridge circuit, a second half-bridge circuit, an inductor circuit, an inductor current detection circuit, and a control circuit. The control circuit is configured to: according to an operating mode, determine one of the first and second half-bridge circuits as a target half-bridge circuit; determine a target switch circuit and a freewheeling switch circuit; control the target switch circuit to be turned on and off periodically; control the freewheeling switch circuit to be turned off when the target switch circuit is turned on; control the freewheeling switch circuit to be turned on when the target switch circuit is turned off; and when an amplitude of a current flowing through the inductor circuit is less than or equal to a preset threshold value, control the freewheeling switch circuit to be turned off.
