摘要： In a power source device for a bubble memory unit consisting of a bubble memory part and a control part, a controlling supply voltage to be applied to both the bubble memory part and the control part is produced by a power source circuit based on a pulse width modulation system. The power source circuit is provided with a circuit which can expand the signal pulse width in excess of its upper-limit value during the ordinary voltage control. When the controlling supply voltage has become lower than a predetermined value, the pulse width is expanded so that the refresh operation may be perfectly executed when the power source device for the bubble memory unit is turned off.

All the driving power sources (602, 702) are turned ON substantially concurrently after the outputs from all the control circuit power sources (601, 701) have reached their normal state, and they are turned OFF substantially concurrently when the output from any one of the control circuit power sources (601, 701) has become abnormal.

摘要： A stabilizing power supply apparatus including, as a switching element, a magnetic amplifier supplied with a rectangular wave voltage produced by an inverter and controlled by a reset current. An error sensing circuit senses a difference between the output voltage of the magnetic amplifier and a reference voltage to produce an error signal corresponding to the sensed difference. An amplifier circuit amplifies the error signal into the reset current for the magnetic amplifier. The amplifier circuit includes a NPN-type transistor for amplifying the control current into the reset current and first and second diodes. The first diode has an anode terminal connected to a negative power supply line and a cathode terminal connected to the collector of the transistor in order that charge will not accumulate on the transistor base. The second diode has an anode terminal connected to the emitter of the transistor and a cathode terminal connected to the magnetic amplifier. The reset current is applied to the magnetic amplifier through the second diode to hold the output voltage of the apparatus constant by regulating the on/off timing of the magnetic amplifier in accordance with the difference between the magnitude of the output voltage and the magnitude of the reference voltage.
