  • Energy regulation circuit and operation system utilizing the same
    Patent number: 10496147
    Abstract: An energy regulation circuit is provided. A first voltage regulator adjusts an input voltage to generate an adjustment voltage. A first energy storage is charged according to the input voltage or the adjustment voltage. A first switch is coupled to the first energy storage. A second energy storage is coupled to the first switch. When the first switch is turned on, the second energy storage is coupled to the first energy storage in parallel. When the first switch is turned off, a second voltage regulator generates an operation voltage according to the voltage stored in the first energy storage. When the first switch is turned on, the second voltage regulator generates the operation voltage according to the voltages stored in the first and second energy storages. A controller operates according to the operation voltage.
