Abstract:
     The invention relates to a method for controlling direct current power employing the first direct current power (2) and one voltage monitoring device (24), said voltage monitoring device monitoring the output voltage of the first direct current power and acting on one controlling device (31), and controlling device controls the working condition for the first direct current power. The invention also provides a power supply device (22), by using which to realize said method. The invention aims to reduce danger of increasing voltage in circuit with a plurality of direct current power, and it employs the second power (3) to change voltage on voltage monitoring device.
