摘要： PROBLEM TO BE SOLVED: To provide an uninterruptible power supply for which a separating means can be tested preventively and automatically under normal operating conditions, thereby insuring the ability to effectively separate inputs from outputs and energy storage portion under emergeny operating conditions. SOLUTION: An uninterruptible power supply (10) includes inputs for connection to a main power supply (1), outputs for connection to an electric load (2), an auxiliary power supply (16), and a selective separating means (14') configured so as to separate the auxiliary power supply (16) from the inputs during emergency operation. First means (26, 28) cause the separating means (14') to establish a reverse polarity state during a test period (ΔT 2 ) under normal operating conditions. Second means (30, 24) monitor voltages proportional to the input voltages (U in ) to the separating means (14'), and then the monitored voltages (U in ) remain at a first reference value (U ref2 ) during the test period (ΔT 2 ), or error signal (DT Error ) is delivered, when if they become higher than this reference value.

摘要： PROBLEM TO BE SOLVED: To provide a voltage detection circuit for controlling the voltage of a terminal to which the power is supplied so as to become a desired voltage, having reduced power consumption, improved voltage detection accuracy, a low ripple voltage and the reduced number of components.
SOLUTION: An output signal of an error amplifier 5 having a reference terminal to which a voltage having no fluctuation of a temperature characteristic is applied and a detection terminal to which a voltage detection terminal VO2 is connected is transferred to a control terminal of a switch element 6. A voltage fluctuation of the voltage detection terminal VO2 is outputted to a detection signal output terminal PC as a current signal by a V-I conversion circuit constituted of a current mirror circuit comprising a constant-current source 4, the switch element 6, a switch element 7 and a switch element 8, through the error amplifier 5. The signal is transferred to the outside by a photocoupler 14, and the voltage of an output voltage terminal VOUT is controlled.

摘要： PROBLEM TO BE SOLVED: To improve the loading current frequency response characteristic of an alternating current electronic loading device to an examined alternating current source device.
SOLUTION: By arranging an inductance for frequency characteristic compensation in series to the source of the transistors for loading current control, the frequency response characteristic of the loading current control feedback loop of alternating current electronic load is improved greatly, and also in the crossover point in which the current polarization changes from positive to negative or vice versa, it acts as alternating current electronic load with very little distortion as compared with the conventional technology, and moreover it can be employed for an examined alternating current source device with much higher frequency than the frequency used by a conventional alternating current electronic load.

摘要： PROBLEM TO BE SOLVED: To provide a power controller which makes more use of energy in a battery before the power is turned off. SOLUTION: A portable radio communication device includes a power controller 315, which monitors a power level input from a battery and also gives power to the rest parts of the radio communication device. The controller 315 includes a boost regulator 407, which is used to generate an internal reference signal that is used over the radio communication device, including an analog-to-digital converter ACD 403 that digitizes battery voltage. The controller 315 compares power with the rest of the parts of radio communication device with a threshold. Further, it is provided with a 2nd comparator 413 which prevents damages to the battery and the radio communication device. The 2nd comparator uses plural lower bound voltage thresholds, in accordance with a power state of the radio communication device.
