  • Publication number: 20240405687
    Abstract: A resonant converter including a full-bridge switch circuit, a resonant circuit, a transformer, a rectifier circuit, a current sensor and a controller is provided. The full-bridge switch circuit includes switches. The resonant circuit is electrically connected to the full-bridge switch circuit and includes a resonant inductor. The transformer includes primary and secondary windings, and the primary winding is electrically connected to the resonant circuit. The rectifier circuit is electrically connected to the secondary winding. The current sensor is electrically connected to the resonant circuit. When a current flowing through the resonant inductor passes through the current sensor, the current sensor generates a current differential signal correspondingly.

  • Publication number: 20240372476
    Abstract: A bidirectional power supply includes an alternating current (AC) port as a source in a first mode and as a load in a second mode and a line-frequency rectifier/inverter to function as a rectifier in the first mode and a set of switches to function as an inverter in the second mode. A bidirectional resonant converter is coupled to a direct current (DC) port with primary-side switches and secondary-side switches respectively arranged on a primary and secondary side of a transformer. A controller controls the primary-side switches and the secondary-side switches by controlling switching frequency based on a determined value while setting time delay between control of the primary-side and the secondary-side switches to be a predefined time delay or by controlling the time delay between control of the primary-side and the secondary-side switches based on a determined value while setting the switching frequency to be a predefined switching frequency.

  • Publication number: 20240094337
    Abstract: According to a method for operating a sensor system, radiation is emitted during a first and a second measurement time period in order to generate point clouds, the points of which are described by a spatial position and an energy characteristic. A first sub-quantity of a first point cloud and a second sub-quantity of a second point cloud are identified with an energy characteristic which is greater than or equal to an energy threshold in each case. A third sub-quantity of the first point cloud and a fourth sub-quantity of the second point cloud are identified with positions lying within the spatial surroundings of the first sub-quantity and the second sub-quantity, respectively. The spatial extension of the fourth sub-quantity is compared with that of the third sub-quantity, and the points of the third and/or the fourth sub-quantity are marked as artifacts based on the result of the comparison.

  • Publication number: 20230152818
    Abstract: According to a method for object recognition by an active optical sensor system (2), a detector unit (2b) detects light (3b) reflected off an object (4) and generates a sensor signal (5a, 5b, 5c, 5d, 5e, 5f) on the basis thereof. A computing unit (2c) ascertains a first pulse width (D1) defined by a first limit value (G1) for the amplitude of the sensor signal (5a, 5b, 5c, 5d, 5e, 5f) as well as a second pulse width (D2) defined by a corresponding second limit value (G2). The computing unit (2c) ascertains at least one property of the object (4) according to the first pulse width (D1) and according to the second pulse width (D2).

A computing unit (2c) ascertains a first pulse width (D1) defined by a predetermined first limit value (G1) for an amplitude of the sensor signal (5a, 5b, 5c, 5d, 5e, 5f) as well as a second pulse width (D2) defined by a predetermined second limit value (G2). The signal pulse is assigned to one of at least two categories according to at least one predefined signal pulse parameter, and a scatter plot for object recognition is generated, said scatter plot containing exactly one entry for the signal pulse, said entry corresponding to the first pulse width (D1) or to the second pulse width (D2) according to the category to which the signal pulse belongs.

  • Publication number: 20220373660
    Abstract: According to a method for filtering measurement data of a sensor system (2), light pulses (5) reflected in the environment of the sensor system (2) are captured by means of an array (7) of optical detectors (8, 9, 10). A multiplicity of measurement signals (11, 12) are generated by means of the array (7) based on the captured light pulses. A computing unit (3) identifies a first measurement signal (11) whose pulse energy is greater than a specified minimum energy, wherein the first measurement signal (11) was generated by a first detector (8). A second measurement signal (12) is compared with the first measurement signal (11) by means of the computing unit (3), wherein the second measurement signal (12) was generated by a second detector (9), which is at a distance from the first detector (8) that is less than or equal to a specified maximum distance. The computing unit discards at least a part of the second measurement signal depending on a result of the comparison.
