摘要： A circuit construction comprising a diode and a capacitor is connected to a secondary coil of a thin transformer such as a wire-type transformer. An excitation energy is discharged during a reset time of the transformer, and this excitation energy is accumulated in the capacitor, thereby output voltage is obtained through the capacitor. A direct current output voltages having two outputs is obtained through one transformer. A small volume and a light weight of the transformer, so that a compact and thin power supply apparatus can be obtained. Since a winding ratio of the transformer can be made small, a copper loss of the transformer can be reduced. It is unnecessary to select a higher switching frequency and a manufacturing cost of the power supply apparatus can be reduced.

摘要： A parallelized power supply system including a plurality of switching power supplies each having a circuit for limiting rush current generated when a main switch is turned on. This system can be installed in an apparatus which requires the functions such as power uninterrupted operation and live wire insertion/dismount. Each switching power supply has another power supply for driving the rush current limiter circuit and a relay circuit for supplying relay driving current and making a connection of relay contacts after a predetermined time lapse after the operation start of the switching power supply. An a.c. power is supplied via the relay contacts to each switching power supply. The relay driving time set in the rush current limiter circuit is different for each switching power supply. Accordingly, concentration and excess of rush current when the relay is driven can be suppressed, and sparks at contact pins of a connector to be otherwise generated when the switching power supply is mounted on the connector, can be eliminated so that radiation noises and connector breakage can be avoided. Each of the switching power supplies connected in parallel has a current detecting resistor connected between the low voltage side of a load and the low voltage side of a voltage regulator d.c. output, and at least one operational amplifier for detecting a change in the d.c. output, the negative power supply terminal of the operational amplifier being connected to the current detecting resistor at its one end on the load side.

摘要： A diode, a condenser and a switching element are connected to a primary winding of a flat type transformer such as a wire type transformer. A citation energy discharged during an off-condition of the switching element, namely a reset period of the transformer, is accumulated in the condenser. An output voltage is obtained from the condenser. Two system direct current voltage output can be obtained from one transformer. Since the two system direct current voltage output can be obtained from the transformer having a pair of a primary winding and a secondary winding, the volume and the weight of the transformer can be reduced and the compact and the slim of the machine apparatus being mounted can be contributed. Making the small winding ratio of the transformer, the copper loss of the transformer can be reduced. By using MOS synchronous rectification, the loss in the circuit can be reduced. It is unnecessary to select highly the switching frequency.

摘要： The invention relates to a power supply system having plural converters connected in parallel. The current of each of the plural converters is detected and each of the converters is controlled so as to match each of the converters to a maximum current value from among the detected current values. In the parallel converters, when one or more converter fails, having an output current of zero, the remaining converters are each partially charged equally to maintain the load current. Since a common bus is arranged between plural converters and plural loads, it is possible to carry out a redundant operation having a high reliability. Since a stable output can be obtained without being affected by the failed converter, a power supply system having the redundancy and the high reliability can be attained.

摘要： Fuel concentration near a power generator of a DMFC is adjusted by decreasing current taken from the DMFC when the concentration near the power generator of the DMFC is higher than an optimum value and increasing the current taken from the DMFC when the concentration near the power generator of the DMFC is lower than the optimum value. Since the fuel does not come into direct contact with the power generator in the DMFC in a portion from a cartridge to the power generator in the DMFC, drying of the fuel is suppressed. By providing an auxiliary tank capable of storing fuel, concentration of methanol supplied near the power generator of the DMFC is lowered upon activation after long-time storage.
