  • Publication number: 20220170965
    Abstract: The present disclosure relates to an apparatus and method for compensating for an offset in switching current sensing in an improved method using a Rogowski coil and an Op-amp. According to the present disclosure, when a Rogowski current sensor and an Op-Amp integrator are used to sense a switching current of a motor driving inverter, a DC-DC converter, or the like, the fact that an offset value of an output of the integrator varies depending on a duty value of a pulse-width modulation (PWM) control signal is used, so that offset calibration software is applied to automatically generate an offset value table at the beginning of power up of a controller and compensate for a sensed value of the current in real time by referring to the value. As a result, there is no need to perform conventional manual tuning.

  • Publication number: 20220159244
    Abstract: The present invention relates to a method and apparatus for setting a reference picture index of a temporal merging candidate. An inter-picture prediction method using a temporal merging candidate can include the steps of: determining a reference picture index for a current block; and inducing a temporal merging candidate block of the current block and calculating a temporal merging candidate from the temporal merging candidate block, wherein the reference picture index of the temporal merging candidate can be calculated regardless of whether a block other than the current block is decoded. Accordingly, a video processing speed can be increased and video processing complexity can be reduced.
