摘要： PURPOSE:To obtain a switching power supply device which is compact and light, has a high power conversion efficiency, and can reduce cost at the time of mass-production by dividing and utilizing a control signal of a switch element of a DC/DC converter for a control signal of the switch element of a booster- type chopper circuit.

Then, after a control signal of a switch element 13 is synthesized by a signal of an input voltage monitoring circuit which is constituted of a resistor 9, a zener diode 10, and a transistor 11 and a NAND gate 8, a control signal to a switch element 6 of the booster chopper is supplied only before and after a zero-cross point of an input voltage waveform, thus enabling a power loss of the switch element 6 of the booster chopper to be small, a power conversion efficiency to be high, and at the same time an inductor 4 to be compact and light owing to drive at a same high frequency.

摘要： PURPOSE:To obtain excellent synchronism between oscillators by preventing interference between the oscillators in parallel operation and by preventing influence upon the operation of the other normal oscillator by a stray preventing diode even when the driving power source of one oscillator stops. CONSTITUTION:When the output of the comparator 6 of an oscillator I changes from a high level to a low level, the output of a logical circuit IC9 goes to the high level and a transistor TR12 turns on. On the other hand, similar voltages are induced across the primary and secondary windings n1 and n2 of pulse transformers PT1 and PT2. At this time, when the comparator 6b of an oscillator II is at the high level, a pulse voltage induced between primary windings A2 and B2 is applied to the route of a terminal A2, capacitor 13b, resistance 3b, and diode 18b to lower the output of the comparator 6b from the high level to the low level forcibly. Further, even if the driving power source of one oscillator stops, a stray preventing diode 14 prevents an influence upon the operation of the other oscillator in normal operation. Thus, excellent synchronism between the oscillators is obtained.

By this repeated operation the conductive width and nonconductive width of the main transistor Q are controlled. By providing limiting circuit LC, the reference voltage Es and another reference voltage E3 are compared each other, the maximum limit of the conduction duration of the transistor is set, and limiting of the maximum conductive width is performed, while the maximum limit of nonconduction width is defined, and limiting of the maximum nonconductive width is performed.
