摘要： The object of the present invention is to provide a bi-directional DC-DC converter having a simplified circuit configuration. Each output of high voltage detection circuit (12) and low voltage detection circuit (15) is inputted to high-voltage side error amplifier circuit (50) and low-voltage side error amplifier circuit (51) independently disposed, which are configured so as to be inverse in polarity, and the output of high-voltage side error amplifier circuit (50) or the output of low-voltage side error amplifier circuit (51) is selected by converting direction switching circuit (22), and the output is inputted to control circuit (25) from PWM comparison circuit (21) being in common with respect to voltage step-up and decreasing operations, thereby driving the first switching element (5) and the second switching element (10). Thus, a inverting circuit conventionally used is not needed, and in addition, only one 3-terminal switch usually complicated in structure is used, and it possible to realize a bi-directional DC-DC converter having a simple configuration as a whole.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
