<p>The present invention relates to a control power circuit of an energy storage device, which can supply stable insulated direct current control power to each of multiple monitor chip circuits of an energy storage system, and which can have a simple circuit constitution by including passive elements mainly included in constituents of multiple direct current control power circuits. The control power circuit according to the present invention comprises: primary control power including a secondary coil to switch input direct current power to output a square wave voltage of a regulated size; multiple insulation transformers each of which includes a primary coil connected to an output of the secondary coil and another coil insulated from the secondary coil; and multiple rectification circuits to respectively rectify secondary output voltages of the insulation transformers and to remove voltage ripples. The primary control power includes a flyback transformer which is switched according to a switch mode power supply (SMPS) principle to output the square wave voltage having the vertically same voltage integration amount according to the time and to transmit energy to the secondary coil by a magnetization current.</p> |
