摘要： The invention relates to a circuit (100) and to a method for controlling and measuring a current (IL) in at least one charge element (101), in particular in at least one laser diode, which can be used at a low operating voltage with laser current control and/or at a low drop in voltage, also for so-called "low power" applications. According to the invention, three MOSFET's (102, 104, 108) are coupled in a split manner for a charge path (103) and for two measurement paths (106, 110) and are maintained by means of an auxiliary controller (107) at the same working point such that they deliver the modulation current and comparison currents (11, 12) which is fixed with respect to the modulation current. The comparison currents are used to determine the average modulation current and to feed a control device (123) which deliver these currents and also the average modulation current to a desired value in which an operational or control current (VA. VB) is varied on a circuit block (114) by the control device. Said circuit block delivers the output signals (S1.S2) when the amplitude depends on the operational or control voltage and which controls two or more circuit elements in the charge path and the measurement path.

摘要： A display apparatus is provided. The display apparatus is a retinal scanning type display apparatus, and includes a low output laser whose operational current is less than that of a standard output laser; a shunting element that is connected in parallel with the low output laser; and a drive circuit that supplies a current to the low output laser and the shunting element. The drive circuit is a drive circuit for the standard output laser capable of adjusting a current value on a discrete basis in a range of an operational current that is higher than the operational current of the low output laser.

摘要： A power efficient device for driving a load comprising a low current path and a high current path, wherein the high current path is driven by a first voltage source. In order to accommodate larger turn on voltages of possible load devices while maintaining low power operation, an additional voltage source exceeding the voltage source in the high current path is introduced in the low current path.

摘要： The invention relates to a method for changing the active number of turns of a control winding (12) in an electric system (10). The control winding is coupled to an AC voltage network for a specified period duration T, is designed for a specified nominal current strength IN, and comprises a first and a second tap (121, 122). The control winding is switched from a first continuous current state, in which a load current flows from the first tap to a load discharge line (15) via a first main path and the second tap is separated from the load discharge line, to a second continuous current state, in which the load current flows from the second tap to the load discharge line via a second main path and the first tap is separated from the load discharge line, according to a specified switch sequence plan. The switch sequence plan specifies that starting from the first continuous current state, the first tap is connected or remains connected to the load discharge line via a first transition path, and the first main path is separated in a switch step a; in a switch step b, the second tap is connected to the load discharge line via a second transition path such that a circuit current iK flows through the transition paths on the basis of the stage voltage between the taps; in a switch step c, the first tap is separated from the load discharge line; and in a switch step d, the second tap is connected to the load discharge line via the second main path; wherein at at least one specified test time tT between switch steps a and c, a test is carried out to determine whether the first main path is separated; a current strength IL of the load current is ascertained; and the test time tT depends on the load current strength IL.
