14. An automated external defibrillator, comprising:
a power circuit comprising:
a battery-driven power source;
a transformer comprising a primary winding and N secondary windings, wherein N is an integer greater than or equal to 2, and wherein the primary winding is electrically coupled to the battery-driven power source;
N charging and discharging branches, wherein the N charging and discharging branches are respectively connected to the N secondary windings and are cascaded in sequence, wherein a first charging branch of the N charging and discharging branches comprises a first capacitor, a first diode, a first inductor, and a second diode, wherein a second charging branch of the N charging and discharging branches comprises a second capacitor, a third diode, a second inductor, and a fourth diode; and
a plurality of electrode plates configured to be connected to an external load, wherein electrode plates of the plurality of electrode plates are electrically coupled to one or more output nodes of the N charging and discharging branches.
