摘要： A semiconductor device for a switching power supply includes first and second external terminals, ON and OFF timing generation circuits, and a drive pulse generation circuit. To the first and second external terminals, a feedback voltage and a voltage induced in an auxiliary winding are input, respectively. The ON and OFF timing generation circuits respectively generate timing signals turning on and off a switching element based on the voltages. The drive pulse generation circuit generates a pulse signal based on these signals. The ON timing generation circuit includes: a bottom detection circuit detecting a lowest point of the voltage of the second external terminal; and a timer circuit, and operates in a PWM mode and a quasi-resonant mode in response to a timing of an output of the timer circuit being before a timing of an output of the bottom detection circuit and the reverse case, respectively.

摘要： A switching power supply device includes a voltage conversion transformer, a primary-side control semiconductor device, a rectification and smoothing circuit, an output voltage detection circuit, a failure detection circuit, and a switch. The primary-side control semiconductor device generates a driving signal which controls a switching element connected to a primary winding of the transformer. The rectification and smoothing circuit is connected to a secondary winding of the transformer. The output voltage detection circuit detects a secondary-side output voltage of the transformer and transmits a feedback signal corresponding to the output voltage to the primary-side control semiconductor device through an insulated signal transmitter. The failure detection circuit detects a failure on a secondary side of the transformer. The switch cuts off a current flowing to the insulated signal transmitter if the failure detection circuit detects a failure.

摘要： A power controlling semiconductor device generates a drive pulse to turn on or off a switching device which applies an intermittent current to a primary side winding of a transformer in response to a voltage proportional to a present current flowing through the primary side winding of the transformer and to an output voltage detection signal from a secondary side of the transformer. The device includes a current detecting terminal and an overcurrent detecting circuit. The voltage proportional to the present current flowing through the primary side winding is applied to the current detecting terminal. The overcurrent detecting circuit compares a voltage corresponding to the voltage applied to the current detecting terminal with an upper limit current detecting voltage to detect an overcurrent. A correction current is applied to a correction resistor connected to the current detecting terminal for a shift in the voltage.

摘要： A resonance voltage attenuation detection circuit detects attenuation of a resonance voltage of a winding of a transformer. The resonance voltage attenuation detection circuit includes a first voltage comparator circuit and a time-out circuit. The first voltage comparator circuit compares a voltage of the winding with a predetermined first voltage. The time-out circuit performs clocking operation in accordance with an output of the first voltage comparator circuit. The time-out circuit outputs an attenuation detection signal when the time-out circuit has clocked a preset period which is shorter than a time required for a peak voltage of the winding to be attenuated from the first voltage to a predetermined second voltage lower than the first voltage.

摘要： When a seat heater and a planar electric heater on a surface of an interior member are used in parallel, the seat heater and the planar electric heater cannot be heated sufficiently due to a limitation on an electric capacity of a vehicle, and in particular, in a vehicle having good engine efficiency, heating of an interior of a passenger compartment by air conditioning utilizing hot air generated by heat expelled from an engine is not sufficient, whereby there sometimes occurs a situation where occupants feel cold. A heating device 2 is provided in a side door panel 1 of a vehicle and a seat heater is made to be heated mainly at an initial stage of heating after an occupant gets in the vehicle, whereas the heating device 2 is made to be heated after a predetermined period of time elapses, whereby the body of the occupant can be warmed quickly and efficiently without making the occupant feel cold physically.

摘要： An insulated DC power supply includes a voltage transformer, a switching device and a primary-side regulating circuit. The voltage transformer includes primary and secondary windings and an auxiliary winding. The switching device causes current to flow intermittently through the primary winding. The primary-side regulating circuit receives a voltage proportional to a current flowing through the primary winding of the transformer, and a voltage proportional to a voltage induced in the auxiliary winding of the transformer to generate and output a drive pulse for turning on or off the switching device. The primary-side regulating circuit includes an ON/OFF signal generator circuit and first and second timer circuits. The switching device is turned off upon expiration of the first timer circuit, and the ON/OFF signal generator circuit does not generate a signal for turn-on of the switching device when the second timer circuit expires.

摘要： An air conditioning seat device includes an air blower, and a dehumidifier for dehumidifying the air sent from the air blower owing to adsorption, and blows out the dehumidified air to holes provided on a skin of a seat through an air duct. In this makeup, the sweat on the body surface and in the clothes is rapidly vaporized, causing a large amount of vaporization heat loss. Accordingly, the human body feels coolness, and steaminess on the skin is suppressed owing to the sweat vaporization.
