The invention provides a control method and control equipment of a bidirectional charging and discharging circuit and the bidirectional charging and discharging circuit. The circuit comprises a first controllable rectification module, a filtering module and a second controllable rectification module which are connected in sequence, the first controllable rectification module is used for being connected with a first power supply, and the second controllable rectification module is used for being connected with a second power supply; the method comprises the steps that when it is detected that the two-way charging and discharging circuit is in a charging mode, in each work period, each switching tube of a first controllable rectification module is controlled to be switched on later and switched off earlier than a switching tube at the corresponding position of a second controllable rectification module; and when it is detected that the bidirectional charging and discharging circuit is in a discharging mode, in each working period, each switching tube of the second controllable rectification module is controlled to be switched on later and switched off earlier than the switching tube at the corresponding position of the first controllable rectification module. According to the invention, the loss of the switching tube can be reduced, heating is reduced, circuit reliability can be improved, and a bidirectional conversion function is realized.
