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 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.

A first foil of a first conductor layer is connected to a common low-impedance power supply. Between the two conductor layers, first ballast capacitors are formed in areas where the first foils are overlapped, second ballast capacitors are formed in areas where the first and second foils are overlapped, and the third ballast capacitors are formed in areas where the second foils are overlapped.

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： A transformer is constituted of an inner core, a plurality of outer cores connected in a ring to the inner core, a primary winding which is fed with a high frequency wave and wound around the inner core, and a secondary winding wound outside the primary winding. The secondary winding has, for the two outer cores, windings which are caused to pass at least once between the inner core and each of the respective outer cores, and the windings passed in the same direction are connected in parallel. With this configuration, it is possible to achieve a transformer for a switching power supply with a low voltage regulation.
