摘要: A multi-phase power converter comprising a plurality of phases for generating an output voltage according to a switching signal and an input voltage, each phase of the plurality of phases comprising a switching element and inductance; wherein the plurality of phases is connected to a common star point, wherein an output capacitor is connected to the common star point. The phases of the multi-phase power converter are not identical in terms of their inductance. Therefore, at least one phase may be optimized for a low current such that, in low power operation, said at least one phase is optimal for lower current levels.

摘要: A method is provided for improving the EMC robustness of Integrated Capacitive Sensor systems with a sensor Signal-Conditioner (SSC). The SSC is connected with a capacitive integrating converter to convert a received signal into a bit stream. An oscillator provides a plurality of sampling frequencies. A counter connected with the capacitive integrating converter collects the bit stream and calculates the digital representative of the physical input which is than stored in an output register. The method includes performing some conversions with different sampling frequencies from the oscillator or a frequency divider by the capacitive integrating Signal-Converter; storing the results of the samplings and using the results in the following cycle to calculate for each sampling frequency a difference to the prior sampling of the same frequency; and calculating the digital representative of the input signal from the external sensing capacitor as the reverse weighted average of the samplings of the different frequencies.

摘要: A switched power converter includes a power stage for generating an output voltage according to a switching signal and an input voltage via a switching element. The switching signal is generated by a variable timing generator which is controlled by a compensator. The pulses of the switching signal are generated on a “need to have basis”. Hence, theses pulses may be generated independently of a PWM period. The pulses can be generated such that switching losses are minimized. A switching pattern can be matched to the load current pattern. Thus, the behavior of the compensator can be synchronized to a regular pattern of the load current. A high resolution variable timing generator may be employed.

摘要: A controller is provided for controlling a power stage of a power converter according to a control law, the control law implementing a specific type of compensator and being pre-designed to generate an objective response of a default power converter for a default parameter value of a component of the power stage. The controller is further configured to determine an actual response for an actual parameter value of the component of the power stage and to alter the control law for the actual parameter value of the component of the power stage such that the actual response matches the objective response. The controller determines a degree of matching between the actual response and the objective response by filtering the actual response to generate a filtered actual response and integrating a product of the filtered actual response and a delayed actual response.

摘要: The invention relates to a UV light sensor produced in a CMOS method, comprising a substrate that has a surface, one or more sensor elements that detect radiation and are designed in said substrate, at least one passivation layer arranged over said substrate surface, and a functional layer that is arranged over said passivation layer and designed in the form of at least one filter. The problem addressed by the invention of providing a UV light sensor which is sensitive exclusively within the UV wavelength range is solved, in terms of arrangement, by means of filters designed directly on a planar passivation layer, and stray light suppressing means around said at least one sensor element and/or around the UV light sensor. In terms of the method, the problem is solved by measuring two output signal from at least two photo diodes fitted with different filters, and by determining a mathematical relationship between the two output signals.

摘要: A switchable power converter includes a switchable power stage comprising an inductor and a capacitor for generating an output voltage according to a switching signal and an input voltage via a switching element comprising a high-side switch and a low-side switch driven by a driver according to the switching signal generated either in a digital control path or a constant-on-time control path. A multi-mode controller is configured to toggle between a light load mode in which the constant-on-time control path is activated and a high load mode in which the digital control path is activated. The multi-mode controller is further configured to generate a control signal for turning on the high-side switch for an additional time when transitioning from the light load mode to the high load mode.

摘要: In a device for determining absolute position of a mobile element in reference to two magneto-sensitive sensors, having a source of a magnetic field fastened to the element, a first sensor signal and a second sensor signal are measured with one magneto-sensitive sensor each. An amplitude ratio of the respective sensor signals and the off-set values about the respective zero point of the sensor signals are determined from the minimum and maximum values of the sensor signals, and from these values, scaled sensor signals are calculated that form a sum signal and a difference signal, which are scaled, with the determination of the minimum and the maximum values occurring by a relative movement of the element over a full range of motion, and an absolute position is calculated via the scaled sum signal and the scaled difference signal.

摘要: In a control method for a power converter, an output voltage is generated according to a control law controlling a switched power stage. During ramp up of the power converter, at least one parameter of the power stage is identified, and the control law is adapted to the identified at least one parameter of the power stage for operating the power converter.
