  "textContent": "The present disclosure provides an energy storage circuit, and a control method. The energy storage circuit includes a DC/DC circuit including a primary side and a secondary side which are connected through a transformer; at least one AC/DC circuit electrically connected between the DC/DC circuit and an electrical grid; a third grid voltage detector configured to measure a grid voltage and detect an on-grid state or an off-grid state; a grid power relay; and a processor. In response to the on-grid state being detected and a grid voltage being detected abnormal, the processor is configured to turn off the grid power relay for disconnection and generate waves using a dual active bridge (DAB) topology mode; and in response to the off-grid state being detected and the grid voltage being detected normal, the processor is configured to determine whether the primary-side voltage is matched with the secondary-side voltage.",
