    摘要: A plurality of power supply circuits Z1′ are provided according to a load capacity. The power supply circuits Z1′ have sides connected in parallel on the side of a direct current input Vi and have sides connected in series on the sides of alternating current outputs Ao. A rectifying circuit DC1 is connected via a resonance circuit Z2 across a combined output of the serially connected sides of the power supply circuits Z1′ on the sides of the alternating current outputs Ao. Switching frequencies are simultaneously controlled by a single control signal outputted from a control circuit S1 based on a direct current output voltage detected from the rectifying circuit DC1 through a detection resistor R5.

    摘要: An open magnetic circuit coil (6) is arranged on a line connecting a battery (1) to a charger (CH1). Furthermore, a resistor (2) is connected in series with a large-capacitance electrolytic capacitor (7) for smoothing a charger output which is connected to the output of the charger (CH1). This can suppress an abrupt change in current flowing in the connection line between the battery (1) and the charger (CH1) in connection between plugs (3a, 3b).

    摘要: Provided is a switching power supply apparatus capable of suppressing heat generation from a power supply to improve the efficiency of conversion during a power supply operation and accurately detecting only a current flowing through a load to achieve more stabile control. Since a first closed loop made up of a fourth diode (27d), a third inductor (25c) and a fourth electronic switch (24d) and a second closed loop made up of a second diode (27b), a first inductor (25a) and a second electronic switch (24b) do not include a fourth inductor (25d) and a second inductor (25b) through which an AC output current supplied to a load (28) flows, an unnecessary current does not flow through the first or second closed loop.

    摘要: An object of the present invention is to provide a switching power supply which can stably determine whether an overcurrent occurs or not on the secondary side. A sample voltage corresponding to a load current value detected by detection resistors R7 and R8 is compared with a reference voltage by an input-side transistor Q4 and an output-side transistor Q3 which compose a first current mirror circuit 14, so that it is possible to determine whether an overcurrent occurs or not. Moreover, a current passing through the output circuit of the transistor Q3 is temperature-compensated by a second current mirror circuit 17 made up of transistors Q6 and Q5.
