  • Patent number: 7839128
    Abstract: In a bidirectional power supply device, a DC-DC converter is connected such that the longer an ON time of the first switch becomes, the higher a voltage of a second positive terminal and a second negative terminal becomes. When stopping the supply of power from a first positive terminal and a first negative terminal to a second positive terminal and a second negative terminal, a control circuit turns OFF a third switch, and then operates a switching signal generation circuit so that the ON time of the first switch becomes a maximum. The switching signal generation circuit is operated so that the ON time of the first switch becomes a maximum with the third switch turned OFF in start-up when supplying power from the second positive terminal and the second negative terminal to the first positive terminal and the first negative terminal.

  • Patent number: 7830035
    Abstract: The power supply unit has a sample-and-hold circuit that samples a voltage supplied from a power source to a load according to a sample timing signal and holds the voltage as an output set value for the DC/DC converter. The unit supplies a load with an output from the DC/DC converter controlled so that an output voltage of a power source becomes an output set value of the DC/DC converter when the voltage of the power source drops. Since a voltage corresponding to the voltage of the power source before the voltage drop is set to the output set value of the DC/DC converter, a stable power supply unit is obtained in which the difference is always small between the voltage of the power source in normal times and the output voltage from the DC/DC converter when the voltage of the power source temporarily fluctuates.

  • Patent number: 7816806
    Abstract: A power supply device of the present invention includes a switching element and a switch that operate so that when a primary DC voltage source of the device is in a voltage drop state, the power of a secondary auxiliary voltage source thereof is mixed with the power of the DC voltage source in a balanced manner and supplied to a load. This structure can reduce the maxim amount of power storage necessary for the auxiliary voltage source and thus the number of power storage elements necessary for the auxiliary voltage source. Thus, a smaller power supply device can be provided.

  • Publication number: 20100091530
    Abstract: A DC-DC converter includes a control circuit which can change the target voltage of the reference voltage source. At the start-up of the DC-DC converter, the PWM control circuit controls so that the first switching element gradually increases the on-off ratio from a minimum on-off ratio; that the second switching element is placed in the OFF state, and that the target voltage is set higher than the normal operating voltage. When the start-up operation is completed, the PWM control circuit controls so that the second switching element starts to turn on and off, and that the target voltage is returned to the normal operating voltage.

  • Patent number: 7679337
    Abstract: A limit value of an output current of power converter is defined as a first current value when a voltage at both ends of capacitor is higher than a voltage at both ends of battery, and a limit value of the output current thereof is defined as a second current value when the voltages are substantially equal to each other, the first current value is set to be smaller than the second current value. Thus, when a voltage at both ends of capacitor and a voltage at both ends of battery are substantially equal, heat is hardly generated. The limit value of the output current is set to a maximum current consumed by load. When a voltage at both ends of capacitor is higher than a voltage at both ends of battery, the limit value of the output current is set to be smaller than the second current value, and thereby heat generation is suppressed. Thus, the size of the heat dissipating components can be reduced, and a power supply system whose entire size can be minimized can be provided.
