  • Direct current conversion device and operation method of the same
    Patent number: 9812961
    Abstract: A DC conversion device including a first DC converter and a second DC converter connected in series, a voltage difference adjusting unit, and a first and a second control unit is provided. The first and the second DC converter respectively receive a first and a second input current to generate a first output current and a first output voltage, a second output current and a second output voltage at a first and a second output end connected to a first and a second energy-storing element, respectively. The voltage difference adjusting unit generates a voltage difference adjusting signal. The first control unit generates a first control signal to control the first converter. The second control unit generates a second control signal according to the voltage difference adjusting signal to control the second converter to balance the first and the second input and output voltages.
