摘要： Disclosed is a small-size, high-efficiency, isolated, bidirectional DC-DC converter. The bidirectional DC-DC converter includes a transformer in which windings are magnetically coupled, switching circuits, a diode which is connected in parallel with a switch, smoothing capacitors, and a control section. First and second DC power supplies, which are connected in parallel with the smoothing capacitors, respectively, provide bidirectional electrical power transfer. When electrical power is to be transferred from the first DC power supply to the second DC power supply, the switch is maintained in the ON state. When, on the other hand, electrical power is to be transferred from the second DC power supply to the first DC power supply, the switch is maintained in the OFF state to prevent a reverse electrical power flow from the first DC power supply.

摘要： A high-efficiency power supply apparatus is provided in light of the reduction of the switching loss. The power supply apparatus connected between the AC power supply and the DC load converts the AC power supplied from the AC power supply to the DC power and supplies it to the DC load. The power supply apparatus comprises the first switching circuit for outputting the switched positive and negative voltages to the primary winding of the transformer, a second switching circuit for supplying the DC power induced in the secondary winding of the transformer and switched to the DC load connected to the second AC terminals, a resonance inductor serial-connected to the primary winding, and a control unit for controlling the switching operations performed by the first and second switching circuits. The control unit substantially short-circuits the second AC terminals by controlling the switching operations performed by the second switching circuit.

摘要： A complex inductor according to the present invention changes its magnetic coupling polarity according to currents flowing its two inductors. The complex inductor includes a first magnetic member, around which first and third windings are formed, and a second magnetic member, around which second and fourth windings are formed. A first inductor is formed by connecting the first winding to the second winding, and a second inductor is formed by connecting the third winding to the fourth winding. The two magnetic members are made of a magnetic material having a magnetic permeability that gradually decreases as its magnetic flux density is increased. When the two windings are interconnected in a direction in which induced voltages generated in these windings by the current flowing in the second inductor weaken each other, the magnetic coupling polarity between the first and second inductors changes according to the current flowing in the inductors. The two inductors are magnetically coupled so that, when one of the two inductors stores energy, the current flowing in the other inductor increases, and when one of the two inductors releases energy, the current flowing in the other inductor decreases.
