摘要： Disclosed is a power supply device comprising a power supplying part (10) that supplies power; a voltage detecting part (30) that detects the level of voltage of the power supplied from the power supplying part (10) using at least one resistor (R1-R4); a switching converting part (20) that switches on/off to allow the power supplying part (10) to output power having a constant level of voltage based on the level of voltage detected by the voltage detecting part (30); and a constant voltage generating part (40) that receives power applied to the at least one resistor (R1-R4), drops a voltage of the received power by a preset normal voltage level, and supplies the dropped voltage to the switching converting part (20), when the level of voltage of the power supplied from the power supplying part (10) gradually increases. With this configuration, a circuit can be protected even when an overvoltage occurs due to an erroneous operation of the voltage detecting part (30) that detects an output voltage.

摘要： The invention relates to a circuit arrangement for improving the interruption behaviour of a switching transistor (T4). Said arrangement contains a pair of complementary transistors (T1, T2), the parasitic capacitance of the switching transistor (T4) being connected in parallel to the primary current section of one of the transistors (T2) and said transistor (T2) being controlled by the other transistor (T1). In a switched-mode power supply equipped with said circuit arrangement, the control circuit for the switching transistor (T4) can operate at a low potential (point A) in comparison to the switching transistor (T4), controlling both the switching transistor (T4) and the other transistor (T1), the latter being controlled capacitively, thus achieving a higher degree of efficiency.

摘要： An inductive load drive device is disclosed comprising: a monitor circuit that inputs the drive-side terminal voltage of an inductive load (ZL) and, when a drive current of the inductive load (ZL) is cut off or rapidly decreased, outputs an operation confirmation signal by detecting a surge current generated by self-induction of the inductive load (ZL), wherein the monitor circuit outputs a confirmation signal that detects a surge produced when a large current flowing in the load due to high voltage applied in an initial period of drive of the load (ZL) is rapidly decreased, wherein in order to prevent confusion of the surge with a surge produced when the load drive is terminated, the operating confirmation signal is masked by using a control signal indicative of the termination of drive of the inductive load.
