摘要： An object of the present invention is to reduce a cost and a power consumption, eliminating a voltage source for generating a reference voltage in an isolated switching power source achieving a feedback from an output side of the power source to a control circuit in an input side of the power source through a photo-coupler. A voltage V.sub.1 obtained by dividing an output voltage V.sub.0 by a voltage dividing resistors 8, 9 is applied to a base of a transistor 11-1 for an error amplifier, and a photo-coupler light emitting element 10-1 is connected between an emitter of the transistor 11-1 and a negative side of an power source output. A forward dropping voltage of the photo-coupler light emitting element becomes approximately constant (approximately 1.1 v) over a variation range of a current flowing to the photo-coupler light emitting element at actually using time. Utilizing such a characteristic, it is possible to cause the photo-coupler 10-1 to have a function generating the reference voltage to be compared with the output voltage V.sub.0 as well as a function achieving a feedback to the control circuit 5 in the input side of the power source.

摘要： A switching power supply is provided in which the efficiency is improved and the regulation and cross-regulation of an output voltage is also improved. Terminals (A) and (B) of a primary winding N1 and secondary winding N2 at which the same polarity is set are interconnected via a first capacitor C4. A tap provided at a given winding position (C) of the primary winding N1 and the other terminal (D) of the secondary winding N2 are interconnected via a second capacitor. Herein, assuming that areas of the primary winding N1 divided by the tap are N.sub.11 and N.sub.12, the number of turns in the area N.sub.11 between the terminal (A) and winding position (C) is nearly the same with the number of turns existing between the one terminal (B) of the secondary winding N2 and the other terminal (C) thereof. Owing to the configuration, an equivalent coupling coefficient observed between the primary winding N1 and secondary winding N2 approaches 1.0. Consequently, the efficiency of a power supply can be improved, and regulation and cross-regulation can be improved.

摘要： A switching power supply, eliminating effect of a potential difference generated in a driving circuit, in which a rapid operation speed of a switching transistor Q1 and a high efficiency are obtained. An auxiliary bias circuit forming a polarity inversion circuit together with the switching transistor Q1 is constructed by connecting a capacitor C3 and a diode D2 in series between a collector of the switching transistor Q1 and a ground, and by connecting a diode D3 and a capacitor C4 in series between a connection point of the capacitor C3 and the diode D2 and a ground. One end of a main current path of the transistor Q3 which conducts when the switching transistor Q1 is in an OFF state, is connected to a connection point of the diode D3 and the capacitor C4 in the auxiliary bias circuit 5a, thereby supplying a voltage obtained in the auxiliary bias circuit 5a to the switching transistor Q1 via the transistor Q3. This voltage is applied as a reverse bias to the switching transistor Q1 and eliminates a voltage between a base and an emitter of the transistor Q3.

摘要： A low-cost and highly reliable flyback isolation-type switching power supply comprises a main transformer and an auxiliary transformer. A secondary winding of the main transformer is connected in parallel with an input winding of the auxiliary transformer. A series network of a diode and a capacitor is connected between the terminals of an output winding of the auxiliary transformer, and a voltage corresponding to the output voltage of the power supply is obtained across the capacitor. The main transformer and the auxiliary transformer preferably share a core having a plurality of bobbin sections, with the windings of each transformer wound around respective different bobbin sections. The equivalent degree of coupling between the secondary winding and the output winding is thus sufficiently larger than the degree of coupling between the primary winding and the output winding.
